I hear ya. I know I have delt myself a handicap here but attempting to bridge the gap some through aerodynamics. While I doubt that I will ever be able to out pull the YS guys, we have a breakout time of 1:25 for 10 laps. Right now my best time is 1:39 and change. Being that I have the long stroke engine I am going to try different pipe lengths and maybe some port work in an attempt to get a 11X10 or 11X11 in the power band.
