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."

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.

You're making me dig through cobwebs, LOL, I almost wanted to post SB Mopar but could not remember for sure..................I really hate to post anything I'm not pretty much 100% sure of. That has me posting less and less nowadays, the old hard drive really taking dumps now.

Rob3865

Yes! The small block Mopar has a few race oriented blocks that have provision for very large needle type cam bearings. They ain't cheap.

amc49

It has been done before, yes. Can't remember exact ones but I know I've seen it. They do it as well to stiffen the cam up when using really radical lobes. The lobes on some specific engines are so tall now that they do it to help stabilize cylinder to cylinder timings. The S&S Harley pro stock bike engines are so radical the timings have to be cut differently for each lobe simply to make them seem to be the same in the real world. The hits from the huge cylinders speed up and slow down the cranks so much that cylinder to cylinder timing jumps around like a b-tch. 5.25" bore X 3.700" stroke, 2.75" intake valve, all at 9500 rpm.

And, I would turn the valve tip down way before I cut on a rocker..............

Wittsend

That is a well written article. It is obviously written from an OHV/ Cam in Block or one piece bearing, OHC perspective.

  The only point I'd disagree with is, "Obviously, the peak lift of the lobe cannot be higher then the outer diameter of the cam bearings - otherwise, the cam could not be installed."  Many modern OHC engines use a split bearing similar to a crankshaft. So, there is no "pass through" restriction of cam bearing size.  Again, I realize the engine type he is referring to in the article. I just didn'twant anyone to think that was a restriction for all engines.

BTW, for higher lift on "in block" designs do they ever go to larger cam bearings?

dick1172762

Thank you rob3865! Maybe this will put an end to this thread and just show that if you could or would machine a late model 2300 roller rocker arm to work on an early cam, it would be ok. I doubt any of us will do so, but it can be done. And why not turn the tip of the valve down to fit the rocker arm?
Its better to be a has-been, than a never was.

amc49

So much for that. Also, you don't harden a cam all the way to the core, rather, you pick a base material of the raw part that is as hard as you want it. Problem with that is, when making thousands of them it will cost you millions more in tooling costs, so you harden the outer surface after machining it while softer. It rarely is more than a few thousandths thick. .100" is a bunch there.

Rob3865

Yes, you are correct. My apologies. I should have known this because in order to increase rocker ratio, the pushrod cup has to move closer to the pivot point. Pretty easy to figure out looking at it from that way. Here is a pretty good read on it that I found.

Higher Ratio Rocker Arms

by Jim Hand, July 1999

[This article originally appeared on Eric Douthitt's, The Pontiac Garage,
website. It now appears here courtesy of the author and Eric Douthitt.]

What are the overall effects of higher ratio rockers? Do they add stress to the engine? Are they safe to use? Do they add power? What precautions should be considered before installing them? The following is a summary addressing these questions.

The basic valve train consists of a cam, or cam lobe, some sort of cam follower, such as a lifter, a push rod, a rocker arm, and the valve (with the associated retainer/keepers, and valve springs). The cam lobe lift is dictated by the dimension from the base circle of the lobe to the lobe centerline, or peak of the lobe. The base circle must be kept large enough to not degrade the strength of the cam, while allowing for enough lift (in conjunction with the rocker arm) to meet all design goals. Obviously, the peak lift of the lobe cannot be higher then the outer diameter of the cam bearings - otherwise, the cam could not be installed. So, in cam design, as more lift is designed in, the base circle becomes smaller in diameter. As the obtainable lift is limited, the lift is multiplied by the rocker arm ratio to bring it up to the desired point(s). If we used rocker arms that had a 1 to 1 ratio, the valve would follow the exact opening and closing as the cam lobe - same peak lift, same opening and closing rate, and same limited valve open area. By making the rocker some greater ratio, such as the standard 1.5, the lift of the lobe is multiplied by 1.5, the opening and closing rates are much faster, and the area under the overall "curve" is much greater. This becomes very obvious by reviewing the graph.


The cam is rated at some duration at .050 lifter/tappet rise. This of course cannot be changed and will remain the same regardless of the rocker arm ratio. However, the valve lift is normally specified with standard 1.5 ratio rocker arms. This can be changed by installing different ratio rockers. As a 1.65 ratio rocker is 10% higher ratio then a 1.50, the lift provided by the 1.65 rocker will be 10 % greater with all cams. This also can be seen on the attached graph. Note that the graph shows a 1.72 ratio rocker, but the action is similar between various ratios. What happens to valve open time with the higher ratio rockers? Because the higher ratio rocker lifts the valve to a higher point in the same time period, it has to lift both quicker and steeper. As the valve begins to open at the same point regardless of rocker ratio, and it opens at the same time as the cam lobe, the duration of the valve opening in crankshaft degrees at the initial opening and closing points is identical to the cam lobe duration. However, because of the quicker and steeper opening/closing rates, the valve open time is greater from any point after initial opening when a higher ratio rocker is used. This is also obvious on the graph. How much more duration? I devised a method to actually measure it. As a standard lobe measuring point is .050 lifter rise, and lobe lifts are normally specified with 1.5 rocker ratio, that means the valve will always be at .075 when the lobe reaches .050" lift (when a 1.5 rocker is installed). By using the .075 point, and determining where it occurs in relationship to the crank in degrees, a yardstick is provided from which to reference any different rocker ratios. As expected, a higher ratio rocker will allow the valve to reach the .075 lift point earlier in the lift cycle (and later in the closing cycle). As the .075 valve lift point is the industry standard when specifying cam duration (1.5 standard rocker ratio X .050 tappet/lifter rise), it becomes a valid reference point. In the Wolverine 234 degree intake lobe, the intake valve was open 4 to 5 degrees longer when measured in reference to the crank when the larger ratio rockers were used. This is also easy to see on the graph.

Summary:

Higher ratio rocker arms open the valve faster, higher, and hold it open for a much greater total period of time as compared to lower ratio units. Does this cause more stress on the valve train? There will be more pressure on the cam lobes due to the friction and pressure caused by the higher lift and resultant greater spring load. However, as compared to providing the same higher lift and effective longer duration with a more radical cam and even stiffer springs, the higher ratio rockers may create less total valve train stress. And such a cam lobe would be very aggressive and would require much heavier springs to keep the lifter from flying off the lobe. Very radical lobes will also add more side stress on the lifters/bores and could possibly cause lifter bore failure. The added pressure on the studs from either higher ratio rockers, or more radical lobe, will be well within the capabilities of modern after market studs.

Wittsend

"Also, the higher ratio rocker doesn't open the valve at any faster rate."

Theoretically the speed is the same to TDC of the cam (or better said BDC on the OHC 2.3). But the valve is (as you state) lifting it further...  sooner. So to a certain level of lift it is getting there faster.

  Meaning at the same amount of duration the lift on the higher ratio rocker will be higher in comparison to the lift on a "normal" ratio rocker.  So, to a given "lift number" (up to the maximum lift of the normal ratio rocker) the higher ratio rocker is faster to that lift point.

Rob3865

Ken has been grinding cams over 30 years. I would have agreed with your heat treating assessment before I talked to him. But he told me some very surprising things. He says all of the factory cams are hardened almost all the way to the core. I was surprised to learn that.

Also, the higher ratio rocker doesn't open the valve at any faster rate. Only a different cam lobe can do that. It does however open the valve further, which as I said, can be accomplished by choosing a camshaft with enough lift to begin with.

'Higher ratio rockers or followers are a useless waste of money.'

I do not concur. There is an effect that can be achieved by popping open a valve faster in some way than the cam itself will do. For want of a better term I always referred to it as the 'gulp factor', an engine may well want that. For one, it can get flow started faster. That phenomenon can be very handy on engines with lower rod ratios since piston spends less time at the TDC rockover. You get more effective working timing.

I have used them many times and never lost power doing so, the point is, if you have them and a cam, the cam is automatically going to be bigger, are you going to walk away from that? No good tuner will. It is much easier to mix and match rockers than cams if motor already has clearance built in for it.

Often the cam numbers you want can be unobtanium as well. Just because someone grinds to any spec does not mean he can do the heat treat processes needed to make some of those grinds live. I can think of some that would shell pretty quick in a regrind.  I have seen regrinds spit their guts out way more than once and these engines are very hard on rockers and lobes if using the slider type. Sometimes the base circle reduction from regrinding can be a problem as well, if enough lobe to warp the stick with every action. Always better to keep base circle big as possible, less valve to valve variation that way.

Of course no insult intended to your regrinder, he may well do re-heattreat.  Many don't though and regrinding costs you the case hardened outer surface. Not the hot setup, I'll take the bolt on rocker there. That hardening is often only like .010" thick.

amc49

I got that disease as well......................even if changing head I like to keep run-in parts together.

Wittsend

This discussion got deep pretty fast. Waldo 786, as to your unanswered question I stated in my post (3rd one) you have to get the right cam.  I did get my cam/rockers out of a wrecking yard.  In my case Pick Your Part at their 50% off sale.  The cam was $12 and the rockers $1 each.  I took the lifters to because at 50 cents each I just couldn't resist.  With all their fees and taxes I was still out the door for under $30.  Maybe it is just "me being me," but I still marked the rockers to make sure they rode on the same cam lobes.

Did you read my post above? For 125 Oregon Cam will regrind your Ranger cam. It might be less. 125 is what they charge foe a V8 cam. I'm not building anything close to a race engine. 125 for a custom roller regrind is a bargain.

But where except a Ranger cam and rocker arms, are you going to get one for under $100? Not everbody is building a race car out of their Pinto.

just an fyi..... the hotrod high story on the cam and different ratio rollers has been 100% proven to be a false theory..... the only place you can get a different ratio roller is from esslinger... and they are pricy.... nearly the price of a new aftermarket cam...all ranger cams have the same lift and profile and the rollers are the same ratio with the difference being the early ones fit 11/32nds valve stems and the late ones fit 7mm valve stems... thats the only difference....

Go all the way to the bottom of the page and click on the red square in the center at the bottom and then choose the style grind. You will see all of the grinds they have available. They will grind any grind you see, even mix and match any lift and duration you see and will grind to any lobe separation for 125 dollars for roller grinds. I have one with them right now getting ground for my bobcat's 302. The four cylinder cams may be less, I don't know. The gentleman's name you want to speak to is Ken. He is very helpful.

Where can I find the specs on a ranger roller cam, and where can I buy one?  Are the ok to buy used say out of a wrecking yard?  These gross lift for the first cam was .420.  I just want a nice cruiser that has a little more power than the stock setup it has now.  Not looking for anything too racy and high rpm.  My goal is to eventually put in an overdrive so I wouldn't be running real high rpms.  I was looking at  top end kit from BoPort that has the springs, retainers, valves, and he also sells the roller rockers.  How can this Crane cam also work with both size rockers and valves as mentioned above as it says it is a replacement for 88 to 98?  This is the first real engine "build" I'm doing so sorry for all the questions.

The problem with the Crane grinds listed there are the same as always for these engines, the lift is too low for the duration. The first lowest choice is already bumping the duration up with almost no increase in lift. I look for at least .060" lift improvement before I even think about another cam, you've got 1/3 that there.  Erson used to make some sticks that used to have say 210 degrees with around .450"-.460" lift and much better cam for these engines. Dunno if they list anything like that anymore and they were more expensive than others. FYI thinking stock lift is around .400" or so.
