Gave a chevy guy a ride home from work he is older than me and more track time my 1970 Formula at the time 2.73 rear 350 eng #47 heads 2800 cam stock shift kit th400 Q'jet about half way home he accused me of lying about my specs
In high school a friend of mine had a 1966 326 4speed 4bbl tempest that thing was NOT night and day from my 1966 GTO 389 4bbl
Bore stroke ratio hamstrings Pontiac at upper HP efforts because of obvious bore size effecting valve / port /flow but from stock to mid HP efforts the Pontiac engine is a fine machine 326 and up
