Okay now I hate these threads as much as the next person, but I want to hear some opinions on this combo.
-Stock shortblock (new rings, main bearings, cam bearings)
-LT4 Heads (no porting, just 3 angle valve job)
-LT4 Intake (gasket matched to the heads)
-52mm T/b (done by myself with a dremel)
-GM847 cam
-Hooker LT's
-True duals with 2 bullet mufflers dumped before the axle
-Moroso CAI
-pcmforless mail order tune (money is tight)

Car is an m6, dual friction clutch, aluminum d/s, 10bolt w/ 4:10s, aluminum flywheel. What kinda HP at the wheels are ya'll thinking? I realize the LT4 heads aren't heads and shoulders above the stock castings without porting but they're what I have. So I'm thinking 360-370rwhp with a good tune. Whatcha think?

 

well its a pretty decent setup... but i think you should go a tad bit bigger than the LT4 stuff. cam looks good from a DD, but i really dont know about true duals...

 

I would think properly tuned it should make about 390 RWHP at least.
