Is an L92 block ok to run under moderate boost?
Is an L92 block ok to run under moderate boost? I picked up an 08 Escalade motor and i was going to put this motor in my car on spray with some ported l92 heads and a cam. At a later date I was going to build a 427 lsx block with a turbo system I have so I can turn up the wick on it and abuse it. I am pondering using the L92 motor under boost.
My question is when will this block give me problems? If I use it under boost it will have forged internals stroked out to 416. I will use and aftermarket casting such as AFR or ETP for a thicker deck. I am mostly worried about head gasket sealing and block distortion under boost.
I don't want to build this motor and start having issues at 13-14 lbs and then have to be stuck at that boost level. I want to be able to throw in the race fuel and crank it up to 18-20 lbs.

Would it be recommended to put a girdle on the bottom end to keep distortion to a minimum? I'm already thinking about putting in aftermarket mains for added strength. Just trying to cover all the bases if I use this motor.
