Re: 1966 GTO 421??

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.
