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?

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

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
