intakes??
Re: intakes?? You want to talk to Jeff "LS1derfull" about this. From what I can remember, I was told the intake does not even flow (cfm wise) as much as a nice set of cycl heads. Aside from that the flow of the lid, MAF, air tubing and everything else can support quite a bit. The intake is sort of the "weak point".
P.S. Why do you want EGR, I removed it from my car and I'm fine.

Re: intakes?? I was talking about the LS6 which comes on the 2001+ cars.
Jeff did some flow bench testing and from the numbers he got it looks like it could hold some power back.
Don't qoute me on this but I think it flowed quite a bit under 300 cfm.
Wish Jeff would chime in here, I don't like to give bogus info.

Re: intakes?? I found Jeff's older post.
"My testing showed 285cfm at .575" lift with Ls6 intake on 243 casting Zo6 head ported by myself. Valves are Ferrea 2.02" with custom grinding to my specs. My 241 castings ported by me, with stock valves flowed 265cfm at same lift with ls6 intake in place."
From what I re-call, that h/c setup made 415 rwhp, so even at that level it appears that a higher flowing intake would benefit to so degree. Probaly at higher RPM.
