Default Edelbrock to Shelby head swap
I have an assembled 427 CO short block that was set up to yield approximately 10.5:1 compression ratio with the Edelbrock 76cc chamber aluminum heads. I got a deal on a pair of Shelby 427 aluminum heads, and I'd like to know what the resulting compression ratio would be. I think the Shelby heads are 82cc (I'm using my memory here, as the Shelby web site is down, so I can't verify this, and may be wrong). The pistons are flat tops w/valve reliefs. The cam is a Competition Cams with just over .600 lift. Can I use these heads on this combination?
