A few near stock 340's I have had never really seemed all that fast from the seat of my pants, but beat nearly everyone I street raced in NJ in the 70's including a 71 LT1
Corvette more than once. 340 Duster had only headers ,Vette was stock walked away from it. NO 350, 351 I ran a could beat the Duster, but there where ALOT
of poorly tuned cars back then running around with mismatched aftermarket parts.
