This is for circle track motors. We're trying to decide if we want to back the timing down and put more gear in the car to help it pull down the straightaways as well as get off the corner faster or if we'd be wasting our time.

Any advice?
Every engine is a little different. IMO, take you motor to the dyno and see what it likes for timing and jetting. This will take all the quess work out of it. Just my 2 pennies anyways.
