18 pounds give or take. Safe is relative to a lot of things.

I am actually curious also. I know for the most part what safe setups are with GT500s When you start changing CR I am not sure. I am sure there is a decent rule of thumb to go by. I just do not know what it is.

The higher the CR the more octane you will usually need to run. There are people out there running 10+ CR and over 25 psi of boost. It really comes down to a few things, What octane you plan on running, how much timing your willing to throw at it, how much fuel you want to give it and then most importantly it will always come down to the tune.

On pump gas, I'd say maybe 18-20psi with the rods & compression you've got.

I thought 18-19psi was really pushing it with pump gas and stock compression?
