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.

Yesterday the spacer went on. It took about an hour total to install, and the throttle bracket did not need to be raised. everything fits under the hood easily too. I have about 15 miles on it so far and about the only obvious difference so far is the idle is considerably smoother than before. I need a little more time to calibrate the "seat-of-the-pants" dyno, but so far it seems to have helped a little in the higher RPM's. Most of my driving is freeway, so I need more time to see if it's stoplight manners are better. Gas mileage figures will be available in a week.

slowride

After spending WAY too much time and money trying to modify a commercial carb spacer, It came down to making one. I bought a piece of 5"x12" .5" aluminum stock, cut it to 5"x6" and started drilling. A mill would have made this go MUCH quicker, but you do with what you have.
This shot shows the carb angle and how the spacer adds 1/2" of plenum and should make the transition into the ports smoother.

I tried to make the plenum hole as close to the flowplate's size as possible to keep the flow as smooth as possible. Theory is that a larger hole would disrupt the flow by creating a reversion (flow trying to go into the hole because of a low pressure area).   

Next is to make a spacer to raise the linkage bracket 1/2" and hope the kickdown rod doesn't need to be modified.

slowride

Well, adding the spacer will be delayed as I bought the one Transdapt makes and it won't seal against the rear of the plenum.  The sealing surface at the back of the plenum is MAYBE 1/8" wide, and it also doesn't leave much meat to mill out for the flow plate. Looks like I'll be buying some 1/2" thick billet and making my own.... :-\

slowride

This will give you an idea what the spacer will look like after milling (this is the bottom view). The flow plate will go down through the center of the spacer and be almost flush with the bottom. Below the plate will be open plenum.

slowride

After mocking up the carb on the intake, I chose to go with a 1/2" spacer. The flow plate under the carb is tapered.... a little less than 1/2" on the front, and a little more on the back). 1/2" will make adapting the throttle linkage easier, as well as (hopefully) keeping it under the hood. I ordered the Transdapt 2134 (open center) since I'll be milling the center so the flow plate just goes through the center. This will put the bottom of the flow plate right at the top of the plenum and provide a smoother bend into the runners.

slowride

My pleasure. After a few days driving it with the header I've become more accustomed to it's "feel". There IS more bottom end as I have a better launch from a stop. The powerband has moved down a bit as I have more pull lower in the powerband than I did before. Gas mileage appears better, but it's really too soon to tell.
Manifold and spacer mods are next and should be interesting.

popbumper

Nice writeup and interesting topic. Thanks for sharing all of this.

Restoring a 1976 MPG wagon - purchased 6/08

slowride

So after 13 miles of freeway, it looks like the collector is sealed and nice and quiet. A little more power at what is probably around 3000 rpm (I haven't installed a tach yet), but the gas gauge didn't move! Hopefully that means better mileage, not another project of replacing the sender..... :smile:

slowride

The header was installed Saturday and it's already been off 2 times. First thing about the Hedman header..... it's a 2 piece with a slip-on collector. What does that mean? It'll leak.... if it's assembled as is. I pulled it off as soon as I got home from the shop to see if maybe they overlooked something.... they didn't. I spoke with a neighbor that works for Doug Thorley and he said they all leak unless you use some type of sealant on the slip joint. That brings me to the second time (this morning). I bought some ultra-copper which may seal it for a short period of time (maybe longer). A ceramic sealant was suggested, I just have to find it. Pulling the header really isn't hard or time consuming, but it HAS to be pulled and assembled in 2 pieces as it won't fit past the bellhousing in one piece. No big deal. Here it is after reassembling it with the ultra copper. I need to give it as much time to cure as possible, so I won't know how well it worked until I leave for work tomorrow morning.
 

Here's a pic of the slip joint at the collector



It is nice how well the header tucks up and doesn't reduce ground clearance



If you're contemplating this, keep a couple things in mind.
Remove the battery and spark plugs..... you'll appreciate the extra room.
Clean the slip joint VERY well. I sanded the surface rust and wiped it down with acetone before applying the ultra copper.
As far as any extra power or gas mileage? I don't have any mileage on it yet to test it.... I'll have a better idea tomorrow.  :D
 

slowride

I made up the air injection port plugs yesterday, pulled the manifold back, and put them in. Went to the muffler shop and set it up for installation on Saturday  ;D I'm hoping to pick a couple miles per gallon as most of my driving is freeway at 60-70 mph. A little extra power wouldn't hurt either....

slowride

Fedex showed up today  ;D
We'll see if the muffler shop is open this Saturday to modify the exhaust

slowride

For the near future I'm running the stock cam. When I get this work done, I'll be pulling the head for machining and possibly make a cam change at that time. This is my daily driver so baby steps are just fine.

78_starsky

Interesting read.  what cam are you goin gto be running with this build? or do you have one in mind?  I have a suggestion if you are doing the full build.

slowride

Well, it's been a while but I'm back to trying out the mods. The header (Hedman 48030) will be here next week and will be the first thing I try. The spare intake manifold will be milled and tested after the header is installed and tested. Last will be the carb spacer to add more plenum. This should give me a good idea what the mods do and how they react to other changes. 

slowride

Well, after having a few beers and staring at the plenum on this manifold, it looks like I need to find a mill and modify the plenum. The primary isn't the problem... it'll feed all 4 runners with little restriction (inefficiently, but relatively speaking). The orange arrows show the flow paths. The problem is the secondary. When the secondary opens, it can flow relatively unrestricted into #2 & 3, but for 1 & 4 it hits the "divider" creating a low pressure area behind it. My understanding of flow dynamics is that the flow hitting the divider will separate the fuel from the air/fuel mixture and create turbulence at the low pressure area behind the divider.  So I'd have #2 and 3 richer that 1 & 4.
My plan is to mill the dividers out of the plenum and round all the runner edges to smooth the flow. In looking at it, it should flow smoother (and more equally) if the flow starts higher instead of moving horizontally in the plenum.  This will require a spacer to lift the carb and extend the plenum higher. The downside is normally adding more plenum (like a tunnel ram) gives you more top end and not necessarily more torque down lower (where I need it).
There's only 1 way to find out...... :surprised:


slowride

I don't really see runner length as the biggest issue since runner size/shape can equalize it to a certain degree (if you wanted to spend that much time on a flow bench). My issue is with how to distribute the A/F mixture evenly considering the primary/secondary orientation. No matter how you change the carb position you are fattening some cylinders while leaning out others. That's why I said a tall plenum with runners at the bottom would provide the best distribution. Unfortunately that merely enhances something the 2.3 has no problem with.... a taller powerband. The manifold I'm playing with is a D5, but I don't know that at the power level I'm at the plenum floor would matter much.

dick1172762

The 74/75 intakes are the ones all the mini-stock boys use when the rules require a 100% stock intake. Its the one with ribs in the bottom, inplace of the later ones with triangles on the bottom. They can be ported to work better, BUT never as good as an equal length manifold. Even Eslingers oval and d-port intakes are of unequal lengths. Only the Eslinger ARCA intake is close, and it wount fit a stock head.
Its better to be a has-been, than a never was.

slowride

I've looked at a couple intakes and there's really no way to equalize the flow and fuel distribution to the cylinders (in a carbureted app) without raising the plenum and bringing the runners in at the bottom of the plenum (similar to the EFI intakes).  Adding more plenum would help, but I would think you'd have to poke thru the hood to do it. It is what it is. It'd be hard to make it worse, eh?

dick1172762

I talked to the Ford enginner in charge of their R&D dyno room in the late 70's about the 2.3 intake manifold, and how to improve it. He told me that it was a bean counter manifold , and made as cheap as possible. Thats why two of the runners are 1/2 the length of the other two. He said that on the dyno, it made no difference in HP reguardless of what carb was bolted on. He said it was the same HP with a stock cab as with a 500 Holley two barrel. He said the flow rate was so poor because of the two short runners, that two runners would run pig rich at all times even when the other two ran lean. LOL.
Its better to be a has-been, than a never was.

71pintoracer

When I was dirt-track racing and had to use the 5200 carb, I would spend about 8 hours modifying the carbs to increase flow. Every little bit helps, and anything in the way disrupts flow. I even cut the ends off of the screws that hold the throttle plates in! Hey, they were in the way!  :lol:
If you don't have time to do it right, when will you have time to do it over?

slowride

Here's the adapter bolted to the carb. The alignment isn't too bad. What DOES concern me is usually I see the thick spacer gaskets between the carb and adapter. This creates a big gap under the carb (between the bores) that may cause flow problems. I have both the spacer type and thin gasket so I'll test both to see if there's any difference performance-wise.

slowride

Thanks Wittsend. I am hand-fitting each piece to make sure I'm doing everything I can to eek out every bit of power. I fit the adapter onto a spare 5200 carb and checked how the throttle bores on the carb align with them on the adapter.  I'll post a pic tonight. Not too shabby for production car stuff......

Wittsend

 I have a lot of appreciation for guys who work hard to get the most out of existing parts.  I can't pull a head/manifold without taking a grinder to it if even just to clean the sharp edges.  I hope you gain a lot for all your hard work.  All the best.
Tom

slowride

These pics should make the concept a little clearer.
This shot is with the adapter on the manifold. Looking in thru the throttle bores you can see the runner entrance to the plenum. As the air/fuel mixture goes down thru bores, it need to make a sharp turn into the runner. 

There was actually a little casting flash at the edge of the runner making the turn even sharper than it appears. The yellow lines show where I radiused the edges to help smooth the transition to the runner.

This could all be academic, but in theory it should help atomization. When you stick your finger down thru the throttle bores you can feel how much smoother the flow should be. With my luck it'll give me another 50 rpm at 6k.  ::)

slowride

I'm going to be playing with the wagon a bit, so I figured I'd start cheap and see what improvements I can make. I'll be adding a Hedman header in the near future, but I wanted to see what I could do with a stock intake. I picked one up from Fred and promptly disassembled it as soon as I got it home.
First, I'm keeping the stock Holley/Weber so the adapter plate will be staying. When you look at the adapter, you'll notice a couple things. The (for lack of a better name) flow plate on the backside of the adapter has a significant mismatch in the throttle bores. I figure it certainly can't help flow, so I'll start by smoothing the bores.

I've smoothed both bores, but have some finish work to do on it. Smoothing the bores more won't buy any more, but I have to have things a certain way. It'll be perfect. While I was at it, I tapped the EGR hole and plugged it, but if I ever want to put it back on I can.
In the plenum on the intake, the runners have very sharp edges as they enter the plenum. I know air doesn't like to turn corners, and it REALLY doesn't like sharp corners, so I've radiused the port edges to smooth flow into the runners. I'll be doing a quickie port match to the head when I replace the intake, but until then there's not a whole lot more I can do with this intake.
Hopefully these little changes will help not only smooth the flow for more rpm, but help atomization by keeping the air/fuel mixture from breaking down when going from the plenum into the runners. Will it wake it up more when I add the header? We'll see......
