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.

Just thought I would add this to the thread. (yes I see it is old) 

This shop reground my 2.8 cam for me. This is all they do are custom grinds. Very nice place to do business with, they work with your old shaft, you send them yours, they grind it to your specs (or tell them what you are looking for) and they will grind, then mail you your cam back. (they also grind lifters to match the cam) check them out.

here is a pic of my grind.

Looking at the roller cam specs it can only have 15° overlap... No wonder all the turbo guys here and turboford have the best results with that cam

Nwstal

I think the reason the stock pinto cam doesnt work well in turbo apps is the overlap if 10° = 5% boost loss then you lose 20% after the computer has adjusted for a set boost level then the O2 Reads rich and it gets confused... The other thing about roller cams at least in most apps the valve opens faster than non rollers in a way giving "longer" duration.  Matt

earthquake

I agree with Pintony on the duration specs.270 deg is a good street cam But 290 deg is getting a little warm,300 to 320 Deg is getting pretty hot for street use.A mild street cam for a motor this size is going to be in the 250 to 260 deg adv duration,Street strip cams will run in the 270 to 280 deg range,and a hot street strip cam will run in the 290 to 300 deg range.Any thing larger than this is really too much for the street and should be considered race only.

BTW: Please don't think the Ranger one is junk just by looking at those numbers. The roller followers have different geometry and they "change" the 'spec.s' as the relate to the valvetrain. From my findings so far it seems that all 2.3 'roller' cams are the same, BUT the followers changed. With my best efforts (so far) I believe that the change was made in iether 93 or 95. The change was made due to the valve stems being smaller in that and later years. I was not able to find a listing for 95 and later followers.

There is a rumor around that the 'Ranger' cam is a performance part (mostly said by ebay sellers). ( It is not, ) it is fairly mild (stock) and the real power benefit is in the reduction of friction; the other benefit is it if FAR more durable and does not loose it's lobes like the sliders do.
Bill


wail doing my own research i came across this info too.  asked the old man about it and was told it was most likely  due to the difference in cam timing and reduced drag (fiction)  that this cam gave  better performance. in regard to tork for use in a truck application. this being said i would say that this is a ford developed performance improvement.  though it is stock in a ranger (and some mustangs) i would call it a pinto performance part. but this is all opinion.  so call it what u like
but its all in how u look at it, i guess

Please Note: I got these numbers from an aftermarket company, not from Ford.

I was told by a NAPA person that all 2.3 slider cams had the same part number, this I found to be wrong on NAPA's web site. Oh, well...

I can tell you that my EFI 2.3T did not like the Pinto cam I had in it, and the 'Ranger' cam has a better torque curve for my set-up.

BTW: Please don't think the Ranger one is junk just by looking at those numbers. The roller followers have different geometry and they "change" the 'spec.s' as the relate to the valvetrain. From my findings so far it seems that all 2.3 'roller' cams are the same, BUT the followers changed. With my best efforts (so far) I believe that the change was made in iether 93 or 95.

Some people have stated that you can interchange roller followers and sliders with either type of cam. I have never done it.

There might be other cams too, but with my 'dial-up' I am not doing any more searches any time soon.

Thanks to all U.S. Military members past & present.

AH.... Yes...
The OLD "advertised" cam duration trick.... ;D
I always forget about that. :idea:

Tony, we could argue all day. This was not my article. Please take a look at this article as they are not using it for a turbo application. BTW the duration they are referring to is " advertised " duration. Still looks good to me as a source of information.

Hey Brad,
Those specs are not realistic for a 4 cylinder
A mild cam for a 4 cylinder are 230 and a hot cam would be 280..

Below is a pretty good article regarding 2.3 cams.

Camshaft & Cam Timing
There are a few things that you must watch out for when modifying your engine for performance. When swapping out your factory cam for a higher performance grind there are a few simple things that you must keep in mind to do a proper swap.

When installing a new cam it is a good practice to install new related components such as tappets springs and retainers.
Never use hydraulic lifters with a mechanical cam or solid tappets with a hydraulic cam. The ramps are not compatible.
Also, it is very important to make sure your valve train can handle the timing events and lobe lift of your performance cam. Check for adequate piston to valve clearance, Spring bind and retainer to valve clearance, spring bind and retainer to valve seal clearance.
It is very important to use camshaft and lifter pre-lube when installing the cam to prevent scoring the lobes during break-in. Engine oil (regardless of its viscosity or quality) is not enough.
Mechanical cams require lash adjustment. If production head is designed for a hydraulic cam, modification is usually required.
When replacing a cam on 2.3L engines it is a good idea since you have most of the front part of the engine disassembled is to replace the timing belt, tensioner, and at least thoroughly inspect the water pump if not replace it for prevention. Also, a adjustable cam pulley is nice since you can advance and retard the cam to find the best setup for your particular application.

In this section the installation of a 2.3L cam will not be covered. For removal and installation of a cam and many other parts on these engines follow this link to turboford.org. Scroll down the page until you get to common maintenance, repairs, and upgrades. Most of the engine, non-turbo related info applies to our engines.

Ford Motorsport SVO, now known as Ford Racing Performance Parts offers a good selection of hydraulic and roller hydraulic cams. All are good for n/a and turbo charged applications. However Ford recommends to not use these cams on vehicles equipped with speed density EFI. Another excellent source of Ford 2.3L OHC engine parts and a wide selection of cams is Midwest Motorsport's located in Kansas City, KS and Ames, IA. Their Phone number is 1-800-262-5033. They have been around for ten years and are a excellent source for almost everything you would need to build a ground up 2.3L. They even sell short and long blocks in multiple configurations.

Esslinger Engineering offers a selection of basically pure racing parts for the 2.3L OHC engine. Some of their products are excellent for street use and others should be left for serious race use only. Their heavy duty timing belt and tensioner and adjustable cam pulley are excellent upgrades to do during a cam swap, they also provide all of the PROPER tools you would need to perform a cam swap.

Here is a general Chart describing some of the basic feature or specs to look for when matching a cam with a specific application.

Duration                              Performance                             Engine/Vehicle Usage
   (SAE)                               Characteristics                           and Modifications
                                                                                               

                                 
                                         

   
270-290
Good idle quality and low rpm torque.
Use with stock or slightly modified engine, stock axle gears and with auto or manual transmission

290-300
Fair idle quality. Good low to mid range torque and horsepower.
Will work with stock or modified engine. Can use with stock axle gears and with A.T. or M.T.

300-320
Rough idle quality. Good mid to high rpm torque and horsepower.
Use with M.T. or high stall A.T. Requires improved carbueration, ignition and exhaust systems. Engine will have lower vacuum than stock.

320-340
Rough idle quality. Good mid to high rpms torque and horsepower. For all out competition only.
Use with M.T. or very high stall A.T. Requires improved carbueration ignition and exhaust systems. Engine will not provide enough vacuum for accessories. Axle gear ratios must be properly selected.


Cam Timing

The Ford Motorsport Cam Sprocket is a good investment at only about 40 dollars from Summit. You can advance and retard timing to suit your particular needs. If you advance your timing you move the peak torque down to a lower rpm, and if you retard timing you add more top end speed. Try 2 degrees advancing and see how it runs. If it responds well try a couple more. Do not exceed 6 to 8 degrees of timing though. Also, the great thing is , the sprocket can be used with a stock cam and also while you are changing the cam be sure to change the timing belt too.

The most important thing to remember is balance. For every action there is an opposite reaction, give and take. Be sure to build up each part of the vehicle. Every system should be matched to the others.
