What year?
And it's not really the bottom end you're going to break due to 15psi - it's more like the pistons due to knock or detonation and the headgasket due to the same.
Safest bet is put an EGT in there and watch the EGTs under boost - along with a scanner when you turn it up to watch for knock and timing retard.
The bottom end on the non commonblock is good up until about 220hp whereas the commonblock is good for - well what I think we've had people running 400+ on it without a problem.
I'm sure others have other views on the subject and I'm sure that there has been somebody who ran a non-commonblock at 350hp for a couple years or something but there are exceptions to every rule =)
