If all you're looking for is 400 hp, your stock bottom end will hold up just fine. They've been shown to hold up to at least 1500 hp with twin turbos, and possibly more. Also, any particular reason for needing to bore out 3mm other than wanting LS1 pistons? Seems like a lot of wasted bores and money for a minor gain in cubes.
