Depends on the block, a late heavy block will do +60 easily if it's not corroded badly and doesn't have horrible core shift.

If you're going big it's best to have the block sonic checked for wall thickness.

I have another motor that I am going to build with the 9.1 cr Titan pistons, with some 264 BC cams and springs with the 1mm oversized valves. I will have a GT4082 on it as well. My goal is 550rwhp-600rwhp, but at the same time I want boost to come on much faster because I love to drag race, and want all the power through the power band. My goal is to have a 7200rpm redline and carry the power to there and be shifting at 7k.
