Big turbo build advice

Im in the middle of my build and having second thoughts. Currently I have a 5.3l iron block that I plan to have bored to a 5.7. I already have the block, a set of Manley valve relief pistons, and callies h-beams and a set of 317 heads. I'm shooting for 1000 on e85. Where do I want my compression to be? I think I'll be around 9:1 with what I have now. Should I try to go lower?

Wow, I figured I'd have to be a lot lower... This'll be my first experience with e-85.

e85 allows you to run more compression and or timing since its a higher octane 105 i think. So 10.1+ probably get the most benefits but i dont have experience with it

Im doing almost the same build and i went with 9.5 to 1 for my e85 build. Going much higher will narrow the tuning window with out much gain in low end power
