We are going to use a Strip Dominator. The compression ratio is still up in the air, but likely no less than 10.5:1. I've got iron headed small blocks running on pump gas at almost 11:1 right now.
I probably should add that I'm big fan of using the parts that the owner already has, and he has a Strip Dominator. I've always wanted to try some things on Strip Dominator. Aaaannnnd we just happen to have and Edelbrock 340 Victor just laying around here on a shelf somewheres.
