A cool Pontiac engineering film between the '70 and '71 GTOs - between a 455HO vs a RA IV 400.

 

 

That was awesome! Thanks for finding it! I have a feeling the new model would always win over old regardless in company stuff lol. 

Gentlemen,  

As of last weekend I have both of those GTO’s.  A 1970 Ram Air IV GTO and a 1971 455 H.O. GTO.  Both 4-speeds.  It will be a while before I can duplicate that video as they both need a lot of work.  The 71 isn’t #’s matching as the block has been replaced with a 1974 455 block with forged crank, rods, & pistons but it’s got legit ‘71 455 H.O. heads, exhaust manifolds, aluminum intake, and carburetor.  Going to be a great driver!

Oh, and it’s not a Judge.  When I bought it I planned on removing the Judge stickers but after having it a couple days I love the way it looks so at least for now I’m leaving it as is.  Laurentian Green with black interior.
