Why the Ford Pinto didn’t suck

Why the Ford Pinto didn't suckThe Ford Pinto was born a low-rent, stumpy thing in Dearborn 40 years ago and grew to become one of the most infamous cars in history. The thing is that it didn't actually suck. Really.

Even after four decades, what's the first thing that comes to mind when most people think of the Ford Pinto? Ka-BLAM! The truth is the Pinto was more than that — and this is the story of how the exploding Pinto became a pre-apocalyptic narrative, how the myth was exposed, and why you should race one.

The Pinto was CEO Lee Iacocca's baby, a homegrown answer to the threat of compact-sized economy cars from Japan and Germany, the sales of which had grown significantly throughout the 1960s. Iacocca demanded the Pinto cost under $2,000, and weigh under 2,000 pounds. It was an all-hands-on-deck project, and Ford got it done in 25 months from concept to production.

Building its own small car meant Ford's buyers wouldn't have to hew to the Japanese government's size-tamping regulations; Ford would have the freedom to choose its own exterior dimensions and engine sizes based on market needs (as did Chevy with the Vega and AMC with the Gremlin). And people cold dug it.

When it was unveiled in late 1970 (ominously on September 11), US buyers noted the Pinto's pleasant shape — bringing to mind a certain tailless amphibian — and interior layout hinting at a hipster's sunken living room. Some call it one of the ugliest cars ever made, but like fans of Mischa Barton, Pinto lovers care not what others think. With its strong Kent OHV four (a distant cousin of the Lotus TwinCam), the Pinto could at least keep up with its peers, despite its drum brakes and as long as one looked past its Russian-roulette build quality.

But what of the elephant in the Pinto's room? Yes, the whole blowing-up-on-rear-end-impact thing. It all started a little more than a year after the Pinto's arrival.

 

Grimshaw v. Ford Motor Company

On May 28, 1972, Mrs. Lilly Gray and 13-year-old passenger Richard Grimshaw, set out from Anaheim, California toward Barstow in Gray's six-month-old Ford Pinto. Gray had been having trouble with the car since new, returning it to the dealer several times for stalling. After stopping in San Bernardino for gasoline, Gray got back on I-15 and accelerated to around 65 mph. Approaching traffic congestion, she moved from the left lane to the middle lane, where the car suddenly stalled and came to a stop. A 1962 Ford Galaxie, the driver unable to stop or swerve in time, rear-ended the Pinto. The Pinto's gas tank was driven forward, and punctured on the bolts of the differential housing.

As the rear wheel well sections separated from the floor pan, a full tank of fuel sprayed straight into the passenger compartment, which was engulfed in flames. Gray later died from congestive heart failure, a direct result of being nearly incinerated, while Grimshaw was burned severely and left permanently disfigured. Grimshaw and the Gray family sued Ford Motor Company (among others), and after a six-month jury trial, verdicts were returned against Ford Motor Company. Ford did not contest amount of compensatory damages awarded to Grimshaw and the Gray family, and a jury awarded the plaintiffs $125 million, which the judge in the case subsequently reduced to the low seven figures. Other crashes and other lawsuits followed.

Mother Jones and Pinto Madness

In 1977, Mark Dowie, business manager of Mother Jones magazine published an article on the Pinto's "exploding gas tanks." It's the same article in which we first heard the chilling phrase, "How much does Ford think your life is worth?" Dowie had spent days sorting through filing cabinets at the Department of Transportation, examining paperwork Ford had produced as part of a lobbying effort to defeat a federal rear-end collision standard. That's where Dowie uncovered an innocuous-looking memo entitled "Fatalities Associated with Crash-Induced Fuel Leakage and Fires."

The Car Talk blog describes why the memo proved so damning.

In it, Ford's director of auto safety estimated that equipping the Pinto with [an] $11 part would prevent 180 burn deaths, 180 serious burn injuries and 2,100 burned cars, for a total cost of $137 million. Paying out $200,000 per death, $67,000 per injury and $700 per vehicle would cost only $49.15 million.

The government would, in 1978, demand Ford recall the million or so Pintos on the road to deal with the potential for gas-tank punctures. That "smoking gun" memo would become a symbol for corporate callousness and indifference to human life, haunting Ford (and other automakers) for decades. But despite the memo's cold calculations, was Ford characterized fairly as the Kevorkian of automakers?

Perhaps not. In 1991, A Rutgers Law Journal report [PDF] showed the total number of Pinto fires, out of 2 million cars and 10 years of production, stalled at 27. It was no more than any other vehicle, averaged out, and certainly not the thousand or more suggested by Mother Jones.

Why the Ford Pinto didn't suck

The big rebuttal, and vindication?

But what of the so-called "smoking gun" memo Dowie had unearthed? Surely Ford, and Lee Iacocca himself, were part of a ruthless establishment who didn't care if its customers lived or died, right? Well, not really. Remember that the memo was a lobbying document whose audience was intended to be the NHTSA. The memo didn't refer to Pintos, or even Ford products, specifically, but American cars in general. It also considered rollovers not rear-end collisions. And that chilling assignment of value to a human life? Indeed, it was federal regulators who often considered that startling concept in their own deliberations. The value figure used in Ford's memo was the same one regulators had themselves set forth.

In fact, measured by occupant fatalities per million cars in use during 1975 and 1976, the Pinto's safety record compared favorably to other subcompacts like the AMC Gremlin, Chevy Vega, Toyota Corolla and VW Beetle.

And what of Mother Jones' Dowie? As the Car Talk blog points out, Dowie now calls the Pinto, "a fabulous vehicle that got great gas mileage," if not for that one flaw: The legendary "$11 part."

Why the Ford Pinto didn't suck

Pinto Racing Doesn't Suck

Back in 1974, Car and Driver magazine created a Pinto for racing, an exercise to prove brains and common sense were more important than an unlimited budget and superstar power. As Patrick Bedard wrote in the March, 1975 issue of Car and Driver, "It's a great car to drive, this Pinto," referring to the racer the magazine prepared for the Goodrich Radial Challenge, an IMSA-sanctioned road racing series for small sedans.

Why'd they pick a Pinto over, say, a BMW 2002 or AMC Gremlin? Current owner of the prepped Pinto, Fox Motorsports says it was a matter of comparing the car's frontal area, weight, piston displacement, handling, wheel width, and horsepower to other cars of the day that would meet the entry criteria. (Racers like Jerry Walsh had by then already been fielding Pintos in IMSA's "Baby Grand" class.)

Bedard, along with Ron Nash and company procured a 30,000-mile 1972 Pinto two-door to transform. In addition to safety, chassis and differential mods, the team traded a 200-pound IMSA weight penalty for the power gain of Ford's 2.3-liter engine, which Bedard said "tipped the scales" in the Pinto's favor. But according to Bedard, it sounds like the real advantage was in the turns, thanks to some add-ons from Mssrs. Koni and Bilstein.

"The Pinto's advantage was cornering ability," Bedard wrote. "I don't think there was another car in the B. F. Goodrich series that was quicker through the turns on a dry track. The steering is light and quick, and the suspension is direct and predictable in a way that street cars never can be. It never darts over bumps, the axle is perfectly controlled and the suspension doesn't bottom."

My Somewhat Begrudging Apology To Ford Pinto

ford-pinto.jpg

I never thought I’d offer an apology to the Ford Pinto, but I guess I owe it one.

I had a Pinto in the 1970s. Actually, my wife bought it a few months before we got married. The car became sort of a wedding dowry. So did the remaining 80% of the outstanding auto loan.

During a relatively brief ownership, the Pinto’s repair costs exceeded the original price of the car. It wasn’t a question of if it would fail, but when. And where. Sometimes, it simply wouldn’t start in the driveway. Other times, it would conk out at a busy intersection.

It ranks as the worst car I ever had. That was back when some auto makers made quality something like Job 100, certainly not Job 1.

Despite my bad Pinto experience, I suppose an apology is in order because of a recent blog I wrote. It centered on Toyota’s sudden-acceleration problems. But in discussing those, I invoked the memory of exploding Pintos, perpetuating an inaccuracy.

The widespread allegation was that, due to a design flaw, Pinto fuel tanks could readily blow up in rear-end collisions, setting the car and its occupants afire.

People started calling the Pinto “the barbecue that seats four.” And the lawsuits spread like wild fire.

Responding to my blog, a Ford (“I would very much prefer to keep my name out of print”) manager contacted me to set the record straight.

He says exploding Pintos were a myth that an investigation debunked nearly 20 years ago. He cites Gary Schwartz’ 1991 Rutgers Law Review paper that cut through the wild claims and examined what really happened.

Schwartz methodically determined the actual number of Pinto rear-end explosion deaths was not in the thousands, as commonly thought, but 27.

In 1975-76, the Pinto averaged 310 fatalities a year. But the similar-size Toyota Corolla averaged 313, the VW Beetle 374 and the Datsun 1200/210 came in at 405.

Yes, there were cases such as a Pinto exploding while parked on the shoulder of the road and hit from behind by a speeding pickup truck. But fiery rear-end collisions comprised only 0.6% of all fatalities back then, and the Pinto had a lower death rate in that category than the average compact or subcompact, Schwartz said after crunching the numbers. Nor was there anything about the Pinto’s rear-end design that made it particularly unsafe.

Not content to portray the Pinto as an incendiary device, ABC’s 20/20 decided to really heat things up in a 1978 broadcast containing “startling new developments.” ABC breathlessly reported that, not just Pintos, but fullsize Fords could blow up if hit from behind.

20/20 thereupon aired a video, shot by UCLA researchers, showing a Ford sedan getting rear-ended and bursting into flames. A couple of problems with that video:

One, it was shot 10 years earlier.

Two, the UCLA researchers had openly said in a published report that they intentionally rigged the vehicle with an explosive.

That’s because the test was to determine how a crash fire affected the car’s interior, not to show how easily Fords became fire balls. They said they had to use an accelerant because crash blazes on their own are so rare. They had tried to induce a vehicle fire in a crash without using an igniter, but failed.

ABC failed to mention any of that when correspondent Sylvia Chase reported on “Ford’s secret rear-end crash tests.”

We could forgive ABC for that botched reporting job. After all, it was 32 years ago. But a few weeks ago, ABC, in another one of its rigged auto exposes, showed video of a Toyota apparently accelerating on its own.

Turns out, the “runaway” vehicle had help from an associate professor. He built a gizmo with an on-off switch to provide acceleration on demand. Well, at least ABC didn’t show the Toyota slamming into a wall and bursting into flames.

In my blog, I also mentioned that Ford’s woes got worse in the 1970s with the supposed uncovering of an internal memo by a Ford attorney who allegedly calculated it would cost less to pay off wrongful-death suits than to redesign the Pinto.

It became known as the “Ford Pinto memo,” a smoking gun. But Schwartz looked into that, too. He reported the memo did not pertain to Pintos or any Ford products. Instead, it had to do with American vehicles in general.

It dealt with rollovers, not rear-end crashes. It did not address tort liability at all, let alone advocate it as a cheaper alternative to a redesign. It put a value to human life because federal regulators themselves did so.

The memo was meant for regulators’ eyes only. But it was off to the races after Mother Jones magazine got a hold of a copy and reported what wasn’t the case.

The exploding-Pinto myth lives on, largely because more Americans watch 20/20 than read the Rutgers Law Review. One wonders what people will recollect in 2040 about Toyota’s sudden accelerations, which more and more look like driver error and, in some cases, driver shams.

So I guess I owe the Pinto an apology. But it’s half-hearted, because my Pinto gave me much grief, even though, as the Ford manager notes, “it was a cheap car, built long ago and lots of things have changed, almost all for the better.”

Here goes: If I said anything that offended you, Pinto, I’m sorry. And thanks for not blowing up on me.

Anyone know about this Edelbrock set-up?

It would be really hard to put a 390 on a 2.0 intake as the 350 is bigger than the hole under the carb. After you install the Racer Walsh adapter, you have to blend the metal under the adapter plate to prevent a step under the carb. You also can use the ERG plate from a 2.3 intake in place of Walsh's adapter plate. No carb that you can put on a 2.0 or 2.3 will give you better mileage than the stock Holley / Weber as long as it is correctly set up. Putting on a EFI lower intake even with a stock carb will be a BIG improvement on a 2.3. The stock carb is plenty big for the street, just the 2.3 intake is JUNK spelled with a capital J. The 2.0 intake is near perfect and there's not much you can do to one.

The 350 will fit on a 2.0 intake (with an adapter). The 390 will not. In this case, cheap is better. The original 390 has been out of production for 25/30 years. The new 390 carb is for small V6's and V8's. It has a power valve unlike the original which had none. Use it and block off the power valve???? Who knows. No one has tried that as far as I know. You could be the first.
Have to look at an intake and see what it looks like, maybe a little machining and an adapter could make the 390 fit???, don't want to plug up the PV though, you have to go up on the jet to compensate and that will make it run fat as heck and kill mileage big time, but on a race deal with a big ole bump stick(with no manifold vacuum)that's a different story, PV's don't work then.

It's funny I come to the Pinto site and find the CBX being added to the conversation. The 1979 was the bad boy or them all, 103 hp (others 98hp) and a total rev monster. The pic I post is one I restored in 2009 and sold in 2011. The white 1982 I've owned since 1983.

Book itself is a gold mine of information for anyone wanting to know in layman's terms how carbs work. Well worth buying, I have a moth-eaten older version lying around somewhere.

amc49

You ain't kidding; I love the sound of that engine, and why people like the sound of V-12 Italian cars as well. Better than the hottest sex........I remember hotdogging a 6-1 CBX along a dark empty freeway one night at around 130 mph and hoping one of the last things I forget as I get older. Came back to dad's garage next day and a guy there who was a regular customer, we did SBC Camaro engines for his street car. He owned a HD dealership in Arlington and bragging about a 1500 cc. hot rod S&S motored Harley he'd built. Needless to say we both started talking crap and I called the friend with the CBX and race on. We had a relatively lonely test strip area, a highway about 7-8 miles long and dead straight and went there. I faced off with him and it was no race but I almost lost the bike the tire was spinning so bad. If you had the balls tire never even thought about grabbing 100% until around 60 mph, then a ultra high speed wheelie. Sometimes it would spin dead straight and sometimes...................well,  those are when you wet your pants....................harder to use your weight and muscle to control spin when bike itself was 600 lbs. The Harley? Pulled your face off but still dead at max 5500 rpm, hell the CBX powerband started at 6000 and went to 10500+. It pissed the Harley guy off I think, he quit coming by shop shortly after that, and Pop cussed me out over it LOL. Yes, Father..................


Vizard claimed the 350 and 500 carbs both work about the same on relatively stock motors, the difference of the 500 only showed with more radical mods to the engine like big cam. He claimed the 350 was easier to hit emissions on than the stock carb was. At one time Holley made a nice progressive 350 (Model #2305??) aimed straight at the four cylinder crowd, it was staged barrels just like the stock 5200 carb. Bet they are hard to find though, a sort of limited market there.

dick1172762

WOW!!! That Honda bike rocks!!! That is a sound to die for. Play that at my funeral please. Beats Scotty on the bag pipes any day. Only saw one car hit that hard, but not that RPM. It was a sprint car out of gear, with no flywheel / clutch.

I have a few intakes on the 2.0 the pony ram, the esslinger 4 mukuni bike carbs ,the holley 390 4 barrel the latter two where on a built 2.0 with an esslinger head and a big crane cam flat tops etc etc etc. For a stock motor the header and a holley 350 should work fine .

Use a Holly 350 two barrel carb on the street. You'll need a Racer Walsh adapter along with a Racer Walsh power valve restricter. Works great on a 2.0L Pinto.

I would think a 500 would be a tad big on a street stocker though?, wonder how a 2.0 intake and 390 would work on a 2.3 on the street, sure would be easy to tune.

Racer Walsh once told me that the stock 2.0 intake with a 500 CFM Holly carb would make only 5 HP less than the dual Weber side draft set up. The Holly set up was what the racer had to use back in the RS class in IMSA. Still have the rule book somewhere  in my shop. The dual carb set up is just for show, nothing else.

You generally recurve when dumping the vac advance and a gas wasting thing to do, big time. All centrifugal in then by 3000 rpm. Sooner is better but today's gas may ping on you. I used to use 36-38 total IIRC. If you recurve with vac advance still there good way to knock holes in pistons.

Seems like I used the vac but bumped the stock mark up like 5 degrees or so sooner. Been awhile. I would have been considering total amount as well.
I'd never dump the vacuum on the street, I was thinking 36 total with 12 initial all in by 2500 and add 15 on the vacuum using manifold vacuum instead of that ported crap just like on V8's, have a smooth idle and good mileage, but don't know if these 4 bangers like a curve like that or not???..

Pretty hard to screw up a two 1 bbl. carb set up, easily done by eye with no special tools unless some idiot has changed the carb linkages to where they do not match in rate. Problem is, it will not stay set, tip in then suffers.

'Most IR  multi carb setups are very drivable if properly sized..............'

You called it right there. Look at the engines and more specifically the size of the INDIVIDUAL cylinders. Then go look up everything you can on the term reversion. It can be controlled on SMALL cylinder sizes but not big. It CAN to a point but with huge work to get rid of the bad reversion side effects. The Pinto manifold in question here was developed around the time IR became the hot topic in gigonda V8 motor pro stock racing, the cylinders were too big and everything tried could not overcome it, not even Edelbrock, every manifold they made with true 100% IR and no plenum sharing made less power than when adding the plenum, which becomes absolutely necessary to absorb reversion pulses from intake pulses striking the back off closed intake valves, or backflowing from long intake timings at lower rpm. Bigger the cylinder the bigger the problem and why you won't see IR even now on carbed super inch engines unless the guy is losing. Head design can't change that although it can hurt or hinder. Your V12s mentioned are smaller cylinders...............the more free flowing the head is the worse the problem.

Plenums are wonderful if you know how to manipulate them. They allow cylinders to share all carb bores, that damps reversion bigtime and allows for smaller carb since all the sharing is going on. When you go to true IR the carb has to be bigger to supply single cylinder per carb and that alone makes the reversion problem worse.

IR works great on smaller bike engines. Lighter weight of bike allows a motor built for high rpm get through the crap running at lower rpm a little easier but the big thing is CV type carb to not open carb all the way even though your right hand says 'yes I want it'. 90% of hotrod carbed bikes have them. Control to make up for reversion and too big carb to make power down low. All getting down to basic physics and functionality whether you want it or not and why engines today are generally smaller. Smaller engines are more 'air active' than bigger and can hit emissions easier for that. Air is easier to manipulate in smaller amounts than in larger, when bigger holes are used you get more turbulence, pressure pulse issues become unsolvable and you just get less air trapped in engine to make power overall size for size. Why you can get 3 hp/cu.in. out of bike motor and strain to get 2 out of car.

IR works on light rods again because of weight and the systems are made for looks and not max power, the throttle bores will always be too small for really good power. Take the effective throat size and compare to swept displacement of one cylinder and then do it on any bike, super difference there. Small bikes can have more carb on them than 1200 hp race engines.................all in the physics of air, its' qualities, and how to handle them. Why you can have a stock bike run to 12000 rpm and no car on earth will (well, maybe a formula car, but look again, the cylinders are bike size!) either, air handling. Why you can't get 1300 hp out of a NA 302 under any circumstances but you can get 65 hp out of a say 17000 rpm Honda six cylinder 250 cc. engine (in 1966!). Same power output there size for size.

http://www.youtube.com/watch?v=eaRop_ZMwo0

Check out the tach and the throttle response, can you say instant?

I got to play with its' big brother, the CBX, with 6-1 header the sound is awesome and pull your face off power. 11.50s dead stock 1/4 mi. with only a header back in 1979 and hazing the tire until 3rd gear. No other bike could do that at the time. First time I ever heard one was like wetting my pants.

By the way a stock 2.0 intake is as good as practically any you will find out there to pay big money for, and according to Dave Vizard. It straps the daylights out of almost anything including some sidedraft setups. I'd stay with it. It sure worked better on my 2.3 than the POS on there, and if building there again it would go right back on any 2.3 engine I made. I'm sloppy and don't like to pay big money and already have a low dog 600 cfm #1850 Holley that I will probably gut and seal the back barrels off of to make a 350 two barrel out of. I don't care what the engine looks like, just how it runs. 350 2 bbl. does pretty well on these Pintos.

And half of it is pure BS. I love Edelbrock stuff but when pressed they spread the same crap as anyone else. NO WAY are 2 accelerator pumps going to have the same gas mileage as one. And the referral to the latest 'trick' IR improvements? We all know where IR ended up on V-8s don't we???? Couldn't be done. The saying the head is well designed, LOL, the 2.0 intake port is dead as far as good power, it is WAY too flat and no shortside radius to make good power at all. All things being equal, tip in performance of bigger barrels off idle is more wasteful of fuel and a dead solid rule there, never mind the added issues when linkage gets loose to let one carb open before the other. Can you say throw away fuel? German heritage? They gave us the VW and two world wars for crying out loud. High airstream speeds when the intake events are lop sided? My side is hurting from all the laughter. You ALWAYS keep airspeeds up with more evenly based intake events, a function of physics there. The 180-540 intake events blow that out of the water.

I'll shut up now, I think I'm losing my voice (or my mind LOL).........................I see Pony Rams everywhere, they're gonna take over the world...............
At risk of doing a belly flop in a Mud Puddle, Let's get even crazier..
If IR is so bad, why are so many Performance setups for street cars working so well? This would include Inline 4,5,6, V6, V8 & V12 motors. As you said, the head design is the problem, not the Fuel delivery approach of IR. Most IR  multi carb setups are very drivable if properly sized for the application and usage. Let's not get caught up in a debate about Cool and Functional .  Otherwise ,we can all just go broke trying to build TBI or TWM systems to replace those nasty carbs...LOL! Back in the 90's I called TWM and told them I wanted to go IR EFI and they said ( with a chuckle) Pinto? Well, Nobody's laughing at the Ricers that cough up the dough for a Civic system now!
Ahh ! The Luddite in me just Fumes when asked to give up my Float bowls ;D

Yes, it is possible to study and become a master of Pintosophy.. Not a religion , nothing less than a life quest for non conformity and rational thought. What Horse did you ride in on?

Soo, is there a good intake setup out there or do you have to make your own?, can't picture this any more complicated than a Chevy IL6????..

And half of it is pure BS. I love Edelbrock stuff but when pressed they spread the same crap as anyone else. NO WAY are 2 accelerator pumps going to have the same gas mileage as one. And the referral to the latest 'trick' IR improvements? We all know where IR ended up on V-8s don't we???? Couldn't be done. The saying the head is well designed, LOL, the 2.0 intake port is dead as far as good power, it is WAY too flat and no shortside radius to make good power at all. All things being equal, tip in performance of bigger barrels off idle is more wasteful of fuel and a dead solid rule there, never mind the added issues when linkage gets loose to let one carb open before the other.

I saved the text on a vintage magazine review on these from when they were reviewed, I forget which magazine (sorry)

here it is... Both performance and economy are available with Edelbrock's new Pony Ram It is very rare when you find a piece of equipment that offers you a performance gain without sacrificing gas mileage or hurting performance in a certain rpm range. The only way you can perform this kind of magic is by increasing the overall efficiency of the engine. This is just what Edelbrock has done. Edelbrock engineers have come up with a manifold for the 2000cc Ford Pinto engine which greatly increases performance throughout the engine's working range while having no adverse effect on gas consumption. The first thing that's apparent when looking at Edelbrock's Pony Ram manifold is that it uses 2 single-barrel carburetors instead of the stock two-barrel or a single four-barrel. According to Edelbrock, it would have been easier to make a manifold that used a four-barrel carburetor, but even the smallest one (in terms of cfm rating) is too much carb for these small engines. You have to be very careful not to eliminate what little low end torque these small engines have. To physically fit a four-barrel on one of these engines requires a manifold with a larger plenum area than what the engine can most effectively use. Also, the relationship of the four throttle bores makes for erratic cylinder distribution on an in-line engine. The design of the Pony Ram started with an examination of the basic flow characteristics of the stock cylinder head, keeping in mind the valve event (lift and duration) of the stock or street/strip-type camshaft. For stock parts the factory head and manifold are basically well-designed units, perhaps due to their German-engineered heritage. Too bad the same thing can't be said of the domestic designed engines of similar size. Quantitatively, the head does not flow a lot of air, and the stock manifold has some subtle features in it to minimize restrictions. A small change in the flow volume, either plus or minus, has a much greater effect percentagewise in these small engines than it would in a larger V-8 type engine. The stock two-barrel carb also has some unique engineering features. The butterflies do not open simultaneously as they do on most carbs of this type. Instead the Pinto unit is more like one-half of a four-barrel, with a primary and secondary throat. A staged throttle linkage allows for a progressive opening. The head, manifold and carburetor(s) must be a compatible unit to achieve a performance increase throughout the operating rpm range. Edelbrock engineers increased the flow characteristics of the unit by designing a manifold with high air stream speeds. This high stream speed principle increases an engine's torque capabilities, especially at low and mid-range engine speeds. Visually, this was accomplished by making two pairs of fairly long runners and connecting them with a small volume plenum. In fact, many of the concepts that go into an I.R. (Individual Runner) manifold were incorporated in the design of the Pony Ram. Each pair of runners is fed by a Holly single-barrel carburetor, part number R-6467, rated at 185 cfm each. These carburetors have been specially calibrated by Holley to be used in conjunction with the Pony Ram manifold. The cost of these carburetors will be comparable to that of a single four-barrel. The manifold, as sold by Edelbrock dealers, come complete with a linkage kit and all the necessary fittings and hoses to hook up the emissions system. Initial tests have shown that the new manifold has better idle emission characteristics than does its stock counterpart. Performance is where the Pony ram really gets it all together. Acceleration times from 0-60, 20-60, 30-60 and 40-60 showed up to a one-second improvement over the stock factory setup. On both setups the engine had been tuned to insure accurate performance data. Week-long mileage checks showed that the Pony Ram did not effect the economy of the vehicle in any measure-able way. The biggest difference is the way the car feels when driving it. You might say that the Pony Ram has made the Pinto a real quarter horse.
It's all about the Pintos! Baby!

I frequent Honda original twincam bike sites because I had a long love affair with them, there is a company that makes the exact same setup but sidedraft for them, it runs but the best way to chop off 20% power and quick. Turns a decent running stocker into a dog. Can't tell the chopper guys anything though, they like it because fits chopped frames. Then they regale you with false tales of how much better they run. Well, yeah, if you can't tune 4 carbs I guess 2 IS easier. So much of the human experience is subject to false interpretation.....................

I believe this was called the Pony Ram System, I remember seeing them for sale when I bought my 72 new.

Back in the 70's and early 80's the roundy round hydro guys had 4 banger classes and the 2.o was "the" motor to have if you wanted to be out in front, seen a lot of custom setups mostly all home made deals but they sure made the power some of these guys were pushing the 3 digit numbers with with them, wasn't interested in them back then now I wished I would have paid attention to that stuff..
