Back to ‘stock’ 340s, I’m putting together a 70 Duster for stock with the 340. I’ve talked to a few running these cars, picking their brain thing. One gent who has raced his 71 since new turns his 7500 when heads up 6500 in bracket mode. Mid to low 10 sec ETs, he said it’s all about the valve springs since all componites have to be same weight and NHRA approved replacement. Makes you do a double take when hood is up and there’s a stock looking engine with cast iron heads and intake with an AVS, running that fast.
Are you buying the engine or building it?
Buying and building, had the ,060 over shortblock with correct balanced internal parts. bought heads, intake, cam-parts from a big time eastern racer. might be outdated a little, but it’s a start. I’ll pull the heads apart to do some molds (to duplicate if needed) touch up the valves and new springs. I’ll try to duplicate a TQ intake from the AVS one in case I want to run it as a 71. So many things to do lol.
