in all honesty, it doesnt matter what gen/motor you have it all depends on your combination. i used to have a nitroused 305 TBI and i especiallly enjoyed it one day when some duche bag at the track with a 00 SS said he'd beat me well funny thing is a 305 tbi nitrous that hooked hard as hell vs a ss all stock everything beat it just because of suspension work vs his stock car. after that run it was nice to see the look on his face to tell him it was a 305 tbi with juice
