nhra factors motors based on weight and trap mph hard to argue that
the best 340 is rated 320 or 325 not going to look it up that is 71 340 with the t/quad
we all know it was luck of the draw on cc of the heads smaller more comp more power
the other non smog 340 ratings are 310 hp and 295hp
the chit carter carb makes 20 hp less then the t/quad
seems this should all be known by 340 a-body people
the 68 340 manual cam smallest cc chambers and t/quad would be the best period
72 340 is 8.5to 1 thats 2 advertised points lower then 10.5 and 10.2 to 1
if the good 340 are lower 9.5 big cc maybe the 72 340 is 8 to 1
bottom line its not making 10 hp more then the highest rated fastest nhra stock
