With the 625 AVS, the 340s were factory rated at 275 hp.
With the 800 cfm TQ, they were 305 hp??? Must have missed it. Where was this stated by the factory?

Factory underrated all 340’s at 275hp the 4 speed cam, the t-quad with the better intake in 71, AVS 340’s around 300hp, 71 340’s closer to 315 and 6 pack a little more. NHRA pegged the actual HP back in the day. 340’s and Hemis were underrated, 383, 440, and 440 + 6 were a lot closer.
