The whole Story
rear wheel HP.I was told it ran flat after 5800.So I changed the cam to Trick flow tfs 30602004 595 int and ex with 1.7 rockers 296,int and ex
duration.I lost 9 hp.It took the engine to 6600 to make 370 hp.
I was took it might need more air and fuel and the LS-2 intake and throttle body coul be the answer.I was also told to check the cats they could be stopped up.This is a stock original engine with 5100 miles. I feel this engine should be over 400 RWH

the LS6 intake and throttle body can be seen here on cars that are putting down WAY more than that. I personally watched my buddies 01 z06 put down over 400 with just bolt ons after tune.

Ginsvette wasn't talking about an LS2 manifold. To put the LS-2 throttle body on an LS-6 manifold you need a bigger nose. In the TPiS test, the LS-6/LS-2 combo was 507.4hp @6800 and the Fast 90/LS-2 combo was 512 hp @ 6800.
