yes, but I've tried the other Race Demon options 825 and 975 with absolutely no difference in 60ft and ET.1.47 60ft? carb too big......lost velocity thusly leading your thinking to the cylinder head. Even in calculating your heads at 100% VE, you only are going to use 941 cfm @ 8000 rpm.
CID x RPM x VE / 3456=CFM consumption at stated RPM figure.
We run a 3400# firebird, 410 SBC, 750 HP carb, Brodix -12 heads, Victor tall intake, 2.250" Lemon headers on 100 av fuel and 10.5:1 CR. Cam is 585/258, trans brake and 3500 stall convertor. 1.118 60FT 9.89 @ 140.
The same thing 65SS and I both said up on top. 112 and 114 are for NOS and Blower applications.....and you are right, Big Al. Compcams has confirmed, that my actual cam has been made for a pro-charger or N20 setup. The camshaft was installed when I took over the engine and was not the right choice for my setup.
