I totally agree the themoquad is the far superior carb, I never claimed a 68 340 was the faster stock 340 motor

just mentioned the hotter camshaft with specs that was mated to my 71 thermoquad motor.

I also ran a 1000 CFM cheater thermoquad for a while with that motor

I recall NHRA rating stock 340's in 71 at either 310 or was it 325 HP.
