How much boost?
it's a tough question to answer. It depends mostly on the tune and octane of gas you are willing to run. Boost is also a horrible way to measure. It's nothing more than a measure of restriction.
I've seen people blow up cars on 5 psi and other live long lives on 10+ psi with stock motors.

Thanks, reason for asking is I talked to the guy I am gonna have tune my engine for me and he told me that after 12 pounds the bearing start to walk and the block gets destroyed, I thought I would get a few second opinions from the guys who have already been there and done that
pushing about 15 or so and Im fine 8.97 to1 I think its more of a fueling question and timing not boost

I agree. I would not use a early aluminum block for high output engine. On sustained high power level gen 3 engines, I have also noted main bearing cap walk.
