make sure you've got a catch can for your radiator (aka radiator overflow) and i think if you run faster than 13.99 you gott have a roll bar. just go and see what happens

Your gonna hit well over 13.9
Heres the deal.
There not idiots at the track, but they will gladly take your money.
The problem is, If you run better than that, You need a roll cage.
That means you will pay the same price as everyone for one run.
I only say this because I have a very similar setup to you, Only I have a 351 instead of a supercharger, 10:1 comp instead of 8.5:1 Trick Flow Heads instead of ported heads
750CFM holley carb w/ Torker II intake Instead of your intake.
All together, probly the same HP. And I can guarntee that I will break WELLLLL into the 12's.

Before you insisted on using the thicker head gasket to lower compression ratio despite our warning you against it due to quench/detonation issues. Now you want to know if you should have the heads milled to increase the ratio? I'm confused....and I suspect you are too.

Rules vary from track to track -- we can tell you all sorts of stuff; but I'd contact the track and see what THEY say. Also, there aren't too many supercharged, sprayed efi motors out there that aren't chipped to optimize things, and to be sure a/f ratios are safe throughout the rev range. Who's doing your chip for you?

And best of all - how is a carbed, aluminum headed 10:1 351 a "very similar set up" to an efi, low compression supercharged 302?
