I'm not sure on boost but there are plenty of LT4s out there pushing over 1000 HP to the wheels on the stock bottom end. I'd say you'll be fine under 1000 RWHP. At 1000 is where you might start having issues. Over 1100 and it's a coin flip.

For the record the trans might hit it's limit around 1000 RWHP also.

BlaqWhole is on the right track, the LT4 is stout out of the box. But tuning & fuel are much more of a definite factor than an actual HP number is. Lean out the fueling too much and you can need new pistons way before 1000 HP...
