[QUOTE=2c5s][QUOTE=Bring the Noise][Sarcasim]Now the magazines that toss a LS7 crate motor on an engine dyno will typically throw on the Dyno headers -vs- GM exhaust manifolds and will use an electric pump which makes the reading optimized (cause it looks great in the magazine and helps to sell more magazines).



Sure. You can make some nice gains by simply tuning a production Z06.

 

Likely yes. Stay tuned.

 

So about that cam question guys,any recommendations?Are my ball park specs close?

 

hummm yeah i would figure that 550 whp could be done with bolt-ons and a very small cam? maybe not though?

 

to get 550 rwhp through a 4l60E, big stall (unlocked), and moser 9 in....you will need about 700 crank hp on a dynojet I believe.

If your friend is concerned with rwhp, have him get a supra or something with a stick The car you described with the parts is nice, and will be fast. Tell him to focus on what it will run in the 1/4...with an auto and moser 9in., that is obviously his forte, not dyno racing. If he doesnt run mid 10's at full weight with some decent traction, I would be surprised.

tell him to get AT LEAST 1 7/8 to 2 in headers....or even 2" headers.

 

Well he's setting up for a race with Kenne Bell Cobra making 700rwhp, so 550rwhp is gonna be about what it takes I figure,but he does have all the traction gear so he does have an advantage out of the hole but needs a certain amount of power to hold off the TOP END charge.
