Also what would the best way to simply change the compression on my motor? BMW guys use different headgaskets, granted the headgasket is a weak spot in those motors but they use them to lower the compression on a stock motor. HG, pistons? And change cam?
Pro-charger kits on LT and LS engines add 100-150 hp with 5-6 psi. You'll need to investigate your engine first to know what power you're making now and what exactly you have. I use the LT and LS engines as examples since they are high compression v8 street motors like your motor.

You can easily change cylinder heads to drop compression. You may even pick up a better cylinder head that will make more power. The beauty of a SBC is the ridiculous amount of parts out there for them. You have so many options that it can be over whelming at times.

Changing cams can also help control your static compression. You'd want to work with an engine builder that really knows boosted engines to make sure it's selected correctly.

If you do go the Pro-Charged SBC route, I'd recommend you work with a engine builder anyway to select a cam. That way you get the most out of the combination. I'd hate to see you go this route only to be underwhelmed. I love seeing different approaches. That's a huge part of why I like this scene.
