You have the cubes/compression/heads/cam.

With a good exhaust/tune you should meat that goal.

How high do you plan on spinning it?

No higher than 6700rpm, my hope is peak power will be around 6500rpm.

This is very similiar to my buildup:

LS2 402
Callies crank/rods
Mahle -12 pistons
ETP 215's @ 59cc w/.040 Cometics
240/244 .609/.612 111+3
SCR 11.56/DCR 8.67(PianoProdigy's calculator)
Ported Fast 90/ported LS2
full bolt-ons EWP, LG LT's, Vararam, etc.

This package will be going in my 02' Z06 and I am hoping for 500whp/500wtq!

Good Luck!

Looks good. But dont be disappointed if you dont reach 500 rwhp. Dynos are tuning tools. The race track is what matters.

Erik is building a 408 for me, very similar to you guys Absolute Speed 5.3 heads, Callies Dragonslayer crank, Compstar rods, Wiseco -10cc, Comp 244.248 .612/.615 112+2. I don't see any way I'm going to hit 500 rwhp since I've got a Ford 9" and that costs about 25 hp. Not having a 90/90 intake costs about 15/20 hp. Erik just built a 408 for a friend of mine, he had the 90/90, 1 7/8 Kooks, and AFR's with a 12 bolt. On a conservative Dynojet he did 485 rwhp.

I have seen a couple of guys mention that they are or will be using the 5.3 heads for their 408/402. I am going to see what kind of power I can get out of the 5.3 heads. If I am lower power wise than I feel it should be the heads will come off and get made up into stage 3. Right now I think I will hit the 500rwhp mark b/c the heads flow well (322@.600 on a 3.9 bore) and they should flow sightly better on a 4 inch bore (with my new motor). Also I still have the wimpy 10 bolt in place and that will save me a few hp over the 12 bolt that will come later this year.
