Theres not much else I can do to the motor and stay within the rules "and I refuse to cheat in the least bit" Buttttttttt I do have the option of going to injection. Right now we have a 650 alky carb on top of a jap knockoff of the nascar air gap manifold also running a velocity stack.we can run injection up to 2 3/16 butterflies. we are running the iron 305 #601 heads and ya can't touch the ports or gasket match. I just need to know if the injection will make any more power or torque ?
I am not Tech. or Dave but I have one question.
Have you had this engine on a dyno and tried different carbs??
The reason I ask is on our IMCA mod. 383 we found 11 hp more by running a Chad Baker carb.
The carb. we had before was a Willis carb.
