Years ago I ran around that compression with a B-trim Vortech and I think it was 12lbs of boost. I had no after or inter cooler or meth or even a custom tune. I ran 93 octane on the street and dumped 116-118 into it at the track. Only other thing I did is at the track I adjusted my 6btm.
This is my first stab at a turbo sbf, but with my old Turbo Dodge, it had much better throttle response and spool up with a little more static compression, I think with either
e85 or meth. it will be ALOT of fun on the street and a complete animal at the track.
What are your goals/ plans for the car???
The compression is fine, DEPENDING on the fuel you choose and amount of timing.
Will it have EFI or a Blowthru Carb??
If it were mine, E85 would be my first and only choice for several reasons. Cost, tuning window (compared to pump gas/meth), cooling capabilities (no intercooler needed). I would buy a 55 gallon drum of it if its not readily available in your area.
With a good tune and fuel, 10.5:1 is totally acceptable. The block will handle upwards of 1300HP, as long as your rotating assembly is forged up, it'll be quite a beast. I plan to go 10:1 on my 327 with Super T76.
