Way too cool B Man! A buddy has an orignal 64 Tripower GTO project that same color!
My college freshman biology TA in 1972-3 was a Pontiac guy. I saw him when I had the Impala SS in the staging lanes at a Dallas race, was good for a few extra points on my next quiz

. He had 2 64 GTOs and multiple old intakes, a bathtub, a M/T crossram. He had put the bathtub once he said. Used a wagon's 2/56 or so rear end to help rpm with the comute. Phil Bauman was his name for any of you Dallas guys that may remember him. Always liked that bathtub intake.
Bet they would sell if someone had the patterns!
