The static ain't s*** it's the DCR that counts. This is cam dependent. The bigger your cam the more static ya can run and be under 9.0DCR.

This subject has been beat to death. There is a LOT of info using the search botton.

I got 11.8:1. I figured out dynamic once but I forgot, think it was just over 9.0. I run 91 octane in the fall,winter,spring and I don't drive it in the summer.
It pings in traffic in the summer here. Phoenix is hotter than most places though, sending IATs way up.

11.1 to 1, 91 octane...highest they sell. runs fine.

12.1 compression with my 396 on 93 octane. Havent gotten the motor together yet. Just have gotten the heads and intake from Loyd Elliott today and they turned out great.
