Tunnel port Pontiac
For what its worth in 70 & 71 we ran a tunnel port Pontiac 455ci in a 65 GTO in NHRA & AHRA without much success. Great idea but we never could get it to run right even when Pontiac tried to help us. Not that it has anything to do with the 302 but same basic idea.
Just my 2 cents
