My original post was to start the discussion on using the E85 in the engine and get the opinions of all - and I appreciate getting them.

Just to clarify, I'm no tree hugger - I'm a Firebird fanatic. And I finally got one to thoroughly enjoy driving around town! I'm also a gearhead - Gimmee power - and if I can have it cheaper by using E85, bonus for me! Yes, it will burn more fuel - but in the long run, if built and tuned correctly, the overall cost per mile (as if that really matters much) should still be less. If not, oh well - it's a First Gen Firebird - it's measured in Smiles per Mile! Overall, I just don't like the idea of having to reduce my compression ratio. I like high compression ratio's, but I don't like detonation or having to add an octane booster. Building it for the E85 I am thinking will be cheaper, and I won't have to modify the heads (much). I have not yet priced things out though. I also just don't know anyone with enough experience to properly modify the heads cheap for me, I'm not going to pay $1000 each to have it done, and I don't want to use other heads. I want the original heads on the engine. That pretty much leaves me 2 options to use pump gas - dish the pistons to reduce the compression ratio (yuk) or raise the compression ratio and use E85. I think I'm going to go with the E85, just to be different.
