Whoops, my bad, I should've stated static compression. For a street motor, go 8 to 1 or a little lower. On the cam, alot of folks sell "blower cams" that have a huge seperation angle. Try to keep it tighter. Talk to the guys at Hughes or Clay Smith Cams. One of my best friends builds quite a few blower motors and goes on in detail about these things, I am no expert at it myself but the info seems to be sinking in to some level or another. I'm wiring a 38 Chevy for him right now that he just finished a blown big block motor that pulled an honest 800 horse on the dyno. (Trust me, he's been showing me that dyno sheet for a month now.)
