hey guys,

i have a built 383 sbc with splayed caps and rock blocked freese plugs down.

runing dart pro 1s 215cc with rme ported exhaust.
bottom end i have a 4340 crank,oliver billet rods, ross custom pistons

cam is a comp roller 292dur,655 lift intake, and 305dur,670lift exhaust
compresion ratio is 10.1 to 1

wanting to run twin garretts in the 70% eff range.

my question is if i run alcohol on this motor what kind of boost can i achieve without much detination.. i know there is probably a lot more variables just wandering what might be posible. thanks andrew
