243s and ls6 cam and Walah you have an LS6. I would suggest getting a set of worked 243s(milled slightly and a good p&p) and a good sized cam (226/230 or 224/228 come to mind). Add a triple disk 34-3600 stall and you have a scary fun ride on your hands.

Boost or spray are about the only options to get over 400rwhp. Even cam heads and every Bolton on the market you won't likely hit 400. 325-375 is the expected range for a cam and heads 5.3 when tuned well. Most people don't understand what 300+ will even feel like because they don't realize these trucks only put down 215ish stock.
