SERB Z06

iTrader: (6)

So I sold my A&A supercharger kit, going back to a simple NA pump gas build.

Car is an 02 Z06 with a stock bottom end LS6, LS2 IM/TB, Advanced Induction 243 heads, and will be getting a SLP Underdrive pulley. Kooks 1 7/8 headers too..

The cam specs are: 230/242 .609/.615 115+3

My question is, will I be leaving a lot of power on the table with this setup making it worth it to swap cams? Or just leave it?

I am also considering a FAST 102 LSXR, do you guys think I have enough supporting mods to see gains from this setup? I know the LS2 intake manifold is not that great NA...

With those mods I'm sure you would see gains with a fast. Esp having worked heads.

I'm no expert but that cam would do fine. Could have a tighter lsa but some say lsa doesn't matter.

I'm sure that intake duration could be more as well. 240. But again I'm no expert.

I run the trex. 610/615 242/248 110.
Stock heads,ls6 intake, ported TB, ARH 1 7/8 LT's.

A better cam and Fast intake will be much more suitable with those AI 243 heads. I'm thinking you might see around a 30 hp gain or so. How come you're going n/a after having a blower?

AI uses a 230/238 with those heads, so I think you will be fine. Add the fast intake, tune and let her rip!

If you plan on staying NA I'd have the heads milled to get the SCR up to 11:1. I'd also go with 4.10 rear gears and at least a FAST 92 intake manifold.

Curious too as to why you're going back n/a,as I have been debating these 2 builds for my car for more than a year

* you said "simpler setup"....what issues have you had *

The split on the 230 242 duration is too big and lsa a lil high imho...not optimal for sure...

Power and drivability goals would be my biggest factors in cam selection...
