I run 93 octane pump gas in my .060" over 340. I have a .557 DC camshaft, 10.2:1 compression with Edelbrock heads (2.02 intake, 1.60 exhaust). I run a factory steel crank with h-beam rods and TRW pistons. It is topped with an Edelbrock Torquer II and a Holley 830cfm carburetor. I have run 11.35et doing the math that is 412hp at the wheels with a 3050lb car (with me). I have run it on my company's Mustang dyno and the hp peak was 409.34hp@6200rpm. I am guessing the flywheel hp is around 470ish. I have the camshaft advanced, I leave at 3000rpm (footbrake), shift at 6400rpm and trap at around 6500rpm with 4.10 gears. I have a best 60ft of 1.50 but usually around 1.53-1.55 depending upon the track conditions.
