Hello guys
it's my first post on this forum but I am following you since a long time.
Here is my story :

I have a 2002 Z06 and I was looking for the best way to upgrade the engine according to my wishes.

First of all this car is my daily driver here around Miami where I live, sometimes driving in downtown, there is a lot of traffic on the I-95 and I can be stuck in the traffic for one hour or more, then I needed a car that could endure this situation and iddle smoothly as close of possible of the stock spec.

I've never race the car and never will, I just want to feel this big torque that normally this BIG (5,7lts) engine has to deliver between 3000 & 5000 rpm, and I want to have a good answer on the first throttle opening when I need to overtake without be forced downshifting to be in the accurate powerband !
I had the car new, 7000 miles today and always service to Kelley-Chevrolet (dealer in Hallandale FL), always filled the tank with premium, and no issues so far (exept the usual leaking).
To summarize:
My goals are not dyno racing with big power between 6000 & 7000 rpm but some numbers around 410 rwhp with reliability, a smooth iddle as stock, a good first throttle opening and a good long & flat torque curve to keep my car really streetable......& fun to drive in the traffic!!!!!!
NOT EASY, I HAD TO COMPROMISE

My car is planned to be tune on the dyno next week at KELLEY and here is the list of mod that we will find on the Z, most are conventional exept for the CAMSHAFT where I decided to go on a reverse split :

Kooks 1 3/4" x 3" with Weld-On Collectors, Stainless Steel,
Kooks 3" x 3" Off-Road X-Pipe

SpringKit Precision Race Components Gold Spring Kit With
Titanium Retainers, Seats & Seals

Texas Speed & Performance Chromemoly 7.40" Pushrods

Rollmaster Double-Roller Non-Heat-Treated Timing Set for LS1

ASP Underdrive Crankshaft Pulley, 1997-03 LS1 Corvette

Donaldson Blackwing Induction Kit, 1997-2004 C5 & Z06

MSD 8.5mm Spark Plug Wires

NGK TR55 Spark Plugs

COMP CAM Grid #LS1 3722R/3720R HR16
Valve timming :
Open INT: 2- BTDC , Close INT: 46 ABDC
Open EXH: 48 BBDC , Close EXH: 8- ATDC
these specs are for cam installed @ 114 ICL
224/220, .581/.581 @ 116 lsa

I will let you know the results, but don't hesitate if you have any suggestions with timing or AFR.
On the other hand have you already an idea of the shape of the power band that we will obtain and what kind of gain in torque ?

results will be coming soon and I will let you know. Is my set up so strange that I can't get any prognosis or diagnosis from you ?

just back from Kelley where Dan tuned the car, everyone was impressed by the # for a "small cam", on the road the Z is simply fabulous, as smooth as stock with more power everywhere and between 6000rpm and 7000rpm there is only fun
