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.

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

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.

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]

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.

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.

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
