A forged buick V6 engine is not a Gen III 4.8L with stock internals. You're comparing apples to oranges. You'll be hard pressed to find anyone around here with a Gen III/IV V8 running 30psi let alone anybody doing it on pump gas.

I'm not sure on how much meth you were running, but I'm sure it's possible on these engines if you're running more meth than pump gas.
