My 466 makes 662HP@6500RPM and 619FT.LBS@5000RPM. using ported CobraJet aluminum heads, 830CFM HollyHP Carb and a COmpCam solid roller cam. 11.4 compression with 74cc heads. It doesn't overheat on the street and I run 93 with about 3 gal of 110 octane without any problems. Tremek TKO 600RR. Best 1/4 time is 10.96@125MPH. I need to straighten out the chassis and I am sure that I can do better. My Superformance weighs in at 2920LBS with 1/2 tank of gas and me in it. If you need my engine specs, contact me at
