Ok heres my issue. I had everything bought for a block i had and found a crack. So different block. Machine shop had to take .010 off to true the deck surface. So now im setting at 9.83 with the other block i was 9.2:1. I can get .070 gaskets and get back to 9.2 or would it be a big deal to run what i already have. Its a 355 iron eagle platinum heads. s480 96mm turbine 1.32 a/r 80mm billet with the race cover. Pump gas here is 91 octane if im lucky. Figure ill run roughly 14#'s of boost

The compression is getting up there but it's nothing that hasn't been done on pump gas before. Cam duration plays a big role in how much compression the engine actually sees as well. I think you'll be fine as long as you keep in mind that your tuning room for error decreases as the compression increases.

Cams 230/236 if im running more static compression basically take it easy on timing to keep cylinder pressures down correct

I wish we had e85 here. I live in WV not many corn fields around here. As far as the meth injection. I did have plans on adding it after i got it up and running. I work in oil and gas so i have very easy access to methanol

Run it and dont think twice about it. 23 degree SBC will do fine at 9.8 and 14 psi on Pump with an air to air intercooler...
