It's relatively hard to get either an LT1 or an LS1 to run well with boost. Their high compression isn't "boost friendly", and many LS1 guys have damaged motors to prove it. There are some that are making great power and have been running well for quite awhile, but in general, they encounter lots of problems when trying to run any more than 5-6psi. Even then, problems are abundant.
5-6psi on an LT1 is worth about 350-375rwhp. 5-6psi on an LS1 is worth 375-400+rwhp with a good tune.
These cars respond amazingly well to juice, and IMO, that is the best way to go fast in them. A good running head/cam car will hit mid-11's with tire and 10's are a button away.
