340 dynoed

I have run a lot of Camshafts and the Clay Smith Camshafts always
perform the best with similar lifts. Never had one go flat either.
Wish I could say that about some of the others I have tested!

I would not hesitate to run 1 3/4 Headers on a 400HP 340 with a
2 1/2 exhaust system.i

30 years ago, we ran in 10's in our 340 Demon stocker with a 460/470 cam
and the heavy TRW pistons in a heavier car... you will like how your car performs.
