1966 GTO 421??
 

I have seen a 1966 GTO at some car shows and it has a 421 cu. inch engine with the tri power set up on it and the guy claims that it is original. Did they ever put 421's in a GTO and did they ever put the tri power on a 421? [img]/ubbthreads/images/graemlins/dunno.gif[/img]

Thats a pretty loaded question [img]/ubbthreads/images/graemlins/laugh.gif[/img]
The RAV thread is a very long thread trying to prove or disprove that a RAV came from the factory.
I think that the general feeling is that no 421 was ever put in a GTO at the factory.
You could get Ace Wilsons Pontiac to install a 421 in your GTO. Possibly thats what happened with this GTO.
To answer your other question...Yes 421s could come with a tri-power.

the only factory installed 421 "small" cars were the factory 63 421SD cars.

Re: 1966 GTO 421??
 

Think of it this way - if you saw a '67 Chevelle and the owner claimed it had a factory 427, would you be suspicious?

Re: 1966 GTO 421??
 

I was always suspicious about the car. This guy has a display he sets in front of the car detailing the options as though it is factory equipment. The next time I see it I will pay closer attention to it and see what, if any documentation he has. A friend of mine has a '64 and a '67 GTO and he was questioning me about it so I posted it here. I don't know that much about Pontiacs.

Re: 1966 GTO 421??
 

There is a thing called PHS, which stands for Pontiac Historical Services. They will send you an invoice of your car.

Next time you see the guy at a show, ask him if he has the factory invoice proving his car is a 421.

As men have fragile egos, at this point you will be on your own. [img]/ubbthreads/images/graemlins/burnout.gif[/img]

Re: 1966 GTO 421??
 

I learned my lesson on egos when I questioned a guy about his '69 Z/28 and he got mad and said it is a z/28 with the 302. [img]/ubbthreads/images/graemlins/bs.gif[/img]It is an X-44 car, column shift auto and factory a/c. I left him alone after that.

Re: 1966 GTO 421??
 

I've had a few run-ins too. Was never questioning the legitimacy of their cars. Just Baby Boomers gone wild. But sometimes people don't know any better.

Re: 1966 GTO 421??
 

I'm pretty sure Royal Pontiac was doing 421 conversions on GTO's by then... but to the best of my (limited) knowledge there were no factory 66' 421 GTO's made

Re: 1966 GTO 421??
 

There was one car that did come from the factory Jim wagners had the 421 put in a GTO for a test car for car & driver magazine at the time they were told it had a 389 in it Jim wanted to really impress the magazine guys and I guess to help sell more cars
It was not till many years later that Jim confessed that car never had a 389 but a 421 and that he pulled one over on car & driver magazine guys

Re: 1966 GTO 421??
 

That car did not come with a 421. It was a transplant.

Re: 1966 GTO 421??
 

Diego:

Did you get to hear John Sawruk speak in Stanton at the PS event? Was WAY COOL. If I'm not mistaken, I believe he had a couple of stories about the 421 swap fiasco.

Re: 1966 GTO 421??
 

The Car & Driver GTOs were 64s when Pontiac 1st came out with them. They had 2, a red one and a blue one. They were both ringer cars for the press built by Royal Pontiac. Someone owns the red one, think the blue one got destroyed, someone made a clone of the blue one.

Hey Rob! [img]/ubbthreads/images/graemlins/smile.gif[/img]

I remember him speaking 2 races ago - is that the one?

However, my memory of those engagements are always a little foggy. Sometimes I have poor memory, other times it's a bit better.

Re: 1966 GTO 421??
 

Nah, it was this past race. Honesty, I wasn't interested when I heard what the topic was gonna be, but it turned out to be VERY interesting.

Re: 1966 GTO 421??
 

So fra, everyone I can think of was interesting.

One of the few things I remember from the recent years' ones was the street race Mattison talked about that happened on 696.

Re: 1966 GTO 421??
 

PMD did not officially put 421's in GTO's for public consumption. There wer some GTO's bulit with 421 from the factory, BUT and that is a BIG BUT, the owners rearly know it. If the factory was short on 389's a it was not uncommon to put a 326 or 421 in to a car slated for some other engins. Ther was NO way the line was going to be stopped for somthing like this. It was common that an engine slated for installation would be pulled from the line by engineering just to test it for tollerances. This would disrupt the sequence for a few cars. Yes, there was a 1966 421 tri power. There were also dealerships that installed 421's as a commom practice. Royal Pontiac, MI, Packer Pontiac MI and FL and Myrtl Motors NY, Gay Pontiac TX, Colony Pontiac FL and others. Hope this helps

Re: 1966 GTO 421??
 

Are you saying that the factory would install an engine that had the wrong vin stamped on it? If they just went down the line with engines, how many could be misinstalled?? Wouldn't this be fraud?

Re: 1966 GTO 421??
 

I think it's an old wive's tale. Using that logic, there's some 326 Tempest out there with a 421.

Re: 1966 GTO 421??
 

I agree, but, it could account for those "freaks' we used to have running around. That is, other than Wanger's "demos". I'm curious to hear what sources Bobcat has for this assertion.

Re: 1966 GTO 421??
 

I hear ya, but what freaks do you talk about? Cars that were running faster than they should?

Speaking of freaks, we're all hung up on 421 cars. It'd be cool to find a 428HO GTO. [img]/ubbthreads/images/graemlins/naughty.gif[/img]

Re: 1966 GTO 421??
 

In our area,"Freaks" were the cars we KNEW were as delivered, but, were significantly quicker than most of that same car. I'd still take a 421 HO over a 428 HO. Just my preference of course.

Re: 1966 GTO 421??
 

There were no 421 GTO's produced(other than the 2 in the 64' article), that "ran out of engines" stuff is nonsense. And I'm a pontiac guy. Jim Wangers has already answered this question several times at shows, I have asked him directly. His response is NO.

Myrtle motors here in NY would swap 428's into 68 and later GTO's and provide RAIV heads,intakes,cams and exhaust as part of a kit that they sold and advertised in car magazines. They claimed to get 13 flat ET's on stock tires. How many swaps they did is a mystery. But they were not from the factory that way.
-------------------------------
By the way the other manufacturers ALL supplied super-tuned cars for road tests.
Wouldn't You?

Re: 1966 GTO 421??
 

You do realize that Jim Wangers' took a hard line that "NO" 421's where put into GTO's at the Factory. It wasn't until a couple of years ago that Jim Wangers admitted that the two '64 C & D cars had 421's. In 1962 there were 6 1962 Tempests with 421's taken to Daytona,one black and five white, one year before the official 421 SD Tempest program everone knows about. YES, in 1966, they built 6 421 Tempests that where also shipped to Smokey Yunick and onto Daytona for testing. These types of cars were/are known as engineering mules. They were built without titles. Even today mules are built without VIN numbers than, supposed to be, crushed. This is do to lawsuites and liablities.These are a few of the ones I know of. There are many more. NEVER SAY NEVER. These cars do not generate paper work for the historic services. GM can't afford to admit they built something that does not comply with the AMA papers they submit to the government . These cars are not for public consumption. Official line will aways be "Didn't happened" I'm sure you have heard of the Delorean's "What If Sessions". Delorean himself drove around a '67 Firebird convertible with OHC 6 with side draft webbers. Pontiac didn't offer it. Does it mean it wasn't built either because Pontiac Historic Services doesn't have the paper work. At least Jack "Doc" Watson finally admited that all of the '68 and '69 Hurst Olds' had factory installed 455's. For years people beleived that Hurst or Demmer Olds did the swaps. Chevy put 427's in Nova' and Camaro's. What, Pontiac didn't have the ability? THINK ABOUT IT Pontiac invented the concept.

Re: 1966 GTO 421??
 

I seem to remember Twelve (12), Six (6) LeMans coupe and six(6) Tempest wagons with factory 421's and aluminum front ends in the 1963 Super Duty program. The LeMans cuopes"; Ray Nichels/Paul Goldsmith Daytona coupe, Stan Long Pontiac, Superior Pontiac, (2)Mickey Thompson, George Delorean. wagon's:Royal had a Tempest Wagon, As did Anderson Pontiac, Hodges Pontiac, Van Winkle Pontiac, Union Park and Arnie Beswick. This not including the 6 421 Tempests built by the factory in 1962 for Daytona testing.

Re: 1966 GTO 421??
 

In 1966 the vin was not stamped into the block. The block number was a unit number that would only be on the paper work. Numbers matching was not an issue at the factory. The date codes are within an exceptable span with most purists. If you look your engine over the heads are not nessarily the same date and time and rarely is the head the same as the block date. The assemblers aren't going to take the time to check date codes or casting #'s. '66 Cars may have
one 092 head and one 093. What than? Tell me would you have noticed? I doubt it. If you had an early or late car you got a hadge podge of parts. They used whatever was in the bin and fit was used.

Re: 1966 GTO 421??
 

Some one wanted my credentials. I'll just scratch the surface.The Source of most of my information. Is I was there for much of it. Family member in engineering depart in '50's through '80's. Family had scrap contracts for GM. Supplied cold roll steel for prototype, production runs and spot buys. Family owned several auto parts stores and machine shops in Detroit area. Some of the employees went on to engineering and suppler companies. Friend was Pontiac assistant line distrbution manager. '66 though 1969 than went onto engineering dept.I keep in touch with a few of them. Freinds worked You'll find me in the credit's of The History Channels "history of the Firbird", The BBC's Jermey Clarkston's "Detroit The Auto Industry", SpeedChannels "MuscleCar" "The Hurst Corporation", I'm in the first paragraph of the "Introduction" of Jim Wangers book glory days. Several past and current pateints are the people you are discussing. From days of old. President Royal Pontiac Club of America. www.Royalpontiac.org, I grew with friends who's fathers where head engineers from different departments and divisions. Family memmber went to Northwood Institute with Roger Smith's daughter Tory and several other dealer and manufacturing executives kids. Do I pass the audition.

Re: 1966 GTO 421??
 

Apparently you are to young or don't recall the law suites against GM in the '70's when it was found out that they had installed Chevy engines in Oldsmobiles. This is why GM now has only has Corporate engines and a central Division called POWERTRAIN.

Re: 1966 GTO 421??
 

Welcome "Bobcat". I only WISH I were too young, and yes, I do recall the Chevy-Olds issue. That still doesn't resolve a question of engines with incorrect VINs being put into cars. Mistakes probably happened, but, there was a post that indicated it was routine to pull engines off the line, and, just go to "the next" one in line. There must have been some precedure to assure that every subsequent car that day didn't receive an engine meant for another car. Maybe you can enlighten us on what they did when an engine was pulled for engineering to test.

Re: 1966 GTO 421??
 

Mike

I'm not sure of the year, was it 67 or 68 that they started putting the VIN on the blocks?

Very special history [img]/ubbthreads/images/graemlins/beers.gif[/img]

Re: 1966 GTO 421??
 

Good info on both posts Bobcat. The official stance from the factory and publications are that no 421's or 428's were factory installed. Special dealers like Royal etc. installed these engines for customers as an upgrade or upcharge. Unless it can be substantially documented as such you would have to agree that a GTO with this conversion would be an incorrect restoration. I disagree with your expanation of non-matching vin numbers in cars and that if one was off the whole line would suffer. One engine may be outfitted for A/C and power steering etc for a vehicle. If the next vehicle in line had or was missing these options the accessory mounting brackets are different as are balancer pulleys and water pump pulleys. Pictures that I have seen show all accessories on the engine before installation into the chassis. The workers would create bigger problems for themselves and really slow down production if they followed your explanation. My friend owned a 70 RA III Judge that was an original paint car and never touched a real survivor by the strictest definition of the term. It had three build sheets and only three owners. The car was ordered as a RA IV but came through as a III. The last digit was a 5 like a IV block should be but was coded a RA III WS block. The VIN on the block and trans was one digit off from the VIN plate. When the VIN number on the block and trans was submitted to PHS it was run through every possible vehicle series . The VIN on the block and trans came back "does not exist" from PHS. The engine and trans never left the engine bay on this car ever. This is an example of a factory mistake that from what I am told happened more than once.

Re: 1966 GTO 421??
 

That is great I have never seen the fixture that GM used to pickup the motors. Makes it easier to understand the brackets that came on the motors from the factory. I had something totally different in my mind.
