u made more power than me, whats the lift on the cam??? it looks like its the Torqer v2,
get a pulley, fast90/90, and u should be in the 450-460whp range, u could also up the comp. by using a thinner head gasket

Bigger manifold/throttle and extractors will get you more power, i think you'll see mid 450s with a retune. Nathan Higgins is the man to see he will point you in the right direction.

Youll will see a nice gain in going from the FAST intake from the LS1 intake, but the harrop is still the best choice assuming you can get your hands on one.
