Went to the track last saturday

With my motor at the time the car would run out of gear and be screaming way too soon before the end of the track with the 456 gear, This was with better heads and strip dominator intake with a 750DP. I was always lead to belive my hydralic cam was the weak link with the tall tire and gear. My buddy with an identical 340 but a more radical solid set up always ran quicker and faster. Guess I was wrong.
