    Default looking for more et from my 4oo

    My 400 + .040 over is at the 12.30,s area, hoping for a couple more tenths with my e heads and new 410 gears but its just not happening. Hei timing at 38 degree,s drag radials on my 67 gto are at 18 pounds. any ideas shoot them at me. Hydraulic crower cam .510 lift, running 1.65,s so it high than that.

    Tell us a bit more about your combo, intake, carb, weight of car, starting line rpm and so on. et, mph & 60' will also help us.

    You will make power with CV-1 heads if you stop thinking of them as a 'Pontiac' head and think of them as a head on a Pontiac block
