Final CR 10.3:1 Max Boost I can run?

i can see you geting at least 12. i plan to run 12 on my 302 with a dss main girdle but i have a blower cam so i dont want nor need anymore boost than that.

I am no expert but I know that what you have to worry about is detonation by the excessive heat caused by the compressed gasses due to compression increases heat. I know a guy with a 2002 SS Camaro that is running 4-5 psi on pump gas. He is getting a intercooler for it and then he will be able to bump it to 8-9 psi on stock boost. If you were running an aftercooler/intercooler I am sure you could run that kind of boost.
