I pulled 385RWHP at Cartek back in February. I have 5.3L Stage II Heads 2.02 valves, titanium keepers, chromoly pushrods, cam (220/224 560/564 114LSA), Hooker LTs, Carsound cats, SLP Lid, Thunder Race MAF ends, SLP CAI, 3" mufflex Ypipe, and Loudmouth. I still have an LS1 intake and no pulley. How much HP do you think is still left in my setup if I was to get an ASP Pulley and the LS6 or new LSX intake? The heads were ported by the Vette Doctors.

Thanks

Ls6 should put you over 400 and the pulley is debatable some have seen 0 on a dyno others have seem as much as 10. But none the less it should hit over 400rwhp with the 2 mods easy.

i'd say those 2 should get u 20hp... y a 220/224 over a reverse 224/220?

 

It was before everyone started doing the reverse cams that I had this stuff done. I just went with whatever the Vette Doctors said to do. I wanted a cam that wouldn't take away from drivability since it is my daily driver.

LS6 intake should bump you over 400 easy, and the pulley generally is good for 5-10hp as well. I've seen more guys pull hp out a pulley then not. Its definitely a mod I'll be going for. When I get my car......
