alot of it's going to depend on your camshaft.we had a 427 with twin 59's and made 18lbs with no problem,probably would have went more but we made our power goal with that.

Asking how much boost you can run isn't a real question. I could weld your exhaust shut and you could run 100lbs of boost. As ninetres said, you need to know how much power you're making or how fast it's going to get an idea. Looks like those turbos make about 450whp on Buick turbo 6s... I'd venture you could make roughly 800whp on them. Boost is irrelevant to a point though.
