Where have you got it set now,,what kind of dizzie are you running?Keep in mind,,that a lot of those crate engines cams,,give you very little leeway past zero on advance.I tried advancing a crate that I had gotton from GM,,and if I remember right,,I could only go as far as 2*BTDC,,send me,,or post,,if you have them,,,all of the cam specs.You're obviously going in the right direction with your tune,,but like you asked,,YES,,advancing will help,,but it will depend on what you have already,,OH,,,and what kind of distributor are you running.
