the intresting thing is since my last post the guys tried a smaller isky that nearly everyone here runs in this class. It is up 20 hp but there is no gain or loss with a 1.6 on intake or exhaust. I am wondering if they should try a break in rocker to see if there is a loss or gain.
Also talking to a local hobby stock racer/machinest that has just quit racing. By going from a rochester to a autolite 1.33 2bbl he typically saw a gain of 10-15 lbs of torque. The cfm is the same but the autolite uses annualar boosters.
