ls6 cam in auto ws6 trans am I have a 2002 ws6 trans am car. It has slp lid, slp bellows, ported tb with bump stop mod, slp dual dual catback, tsp 1 3/4 lt headers, 3 in. ory, and circle d 3200 278mm converter. How much improvement would the stock 02 ls6 cam be over my stock cam? I also plan on putting stock 243 heads with a cnc competition valve job by advanced induction. How much hp and tq. will the ls6 cam and 243 heads give me at the wheels on my car? Will this combo and my other mods be able to put my car in the 12.5 or better range in the 1/4 mile.
It will be an improvement over your current cam. But you'll spend more on fluids and gaskets and you'll need springs anyway. Idvguess 15-20 hp from the cam. There are much better cams available honestly.
Going from your stock LS1 cam and heads to an LS6 cam and LS6 heads with a competition valve job from Ai should definitely provide a noticeable increase in power and torque throughout the rev range. I'm gonna throw out a gain of 40rwhp give or take. I'm thinking 15rwhp from the cam and 25rwhp from the heads with the valve job taken into consideration.
FWIW, stock '02-'04 LS6 C5Zs typically dyno around 40ish rwhp more than '01-'04 LS1 C5s from what I've seen. The main differences being the LS6 heads and cam so just some food for thought.
Regarding the LS6 cam, if you want a car that literally drives stock, wanna keep things on a budget, want a smooth stock like idle and want to fly under the radar it's not a bad way to go. Now, you can make a good bit more power utilizing a larger aftermarket cam which would be my personal preference but it's all in what YOU want and what works best for YOU. I could see you easily achieving your 12.5 in the 1/4 goal given your current setup with the addition of an LS6 cam and LS6 heads with competition valve job.

Here is a dyno graph that AI posted a long time ago of an ls1 with their 219cc 241 heads, it shows a stock ls1 cam vs ls6 cam. The 449.56 is without accessories. You gotta shift the ls6 cam pretty high to really make it shine. Nevertheless, the ls6 cam with a good set of heads will surprise a lot of people.

Verdad Gallardo Since you asked for recommendations id recommed our new high lift hot cam
I have had 2 guys recently choose it over a vinci torque master or whatever they call it
The kit is 515 for cam and springs or 575 for cam springs and pushrods. easy on the valvetrain ans very quiet. uses stock prs also or you can upgrade to the heavy duty ones
Made 385/365 on an ls1 with 853 heads speed eng headers tsp exhaust and ls6 intake
Doesnt need a stall but works great with one also. doesnt need gears either but works better with them.

Normally you measure overlap at .050 itll give you a better answer as to how it will react.

I don't want a cam with that much lift. I want one under 580 so I'll get more valve spring life. Also that cam has more lope than I want. It sounds good, but i want a less lopey cam. I appreciate the recommendation though.
Having more lift does not mean accelerated spring wear.
Anyone including us can design you what you want, but honestly you can tame the lope in the tune.
That cam has 1* of overlap at .050

2001 - 2002 Fbody
197/207 int/exh @ 0.05" duration
0.467" / 0.479" int/exh lift 116 LSA
2002+ LS6 cam
204/218 int/exh @ 0.05" duration
0.551" / 0.547" int/exh lift 117 LSA
I would consider the LPE GT2-3 cam over the LS6 cam.
207/220 duration @ .050 lift -.571/.578 lift 118.5 LSA
Likewise, for mild Cams these two old favorites from Comp Cams usually do pretty well.
XR269HR, 216/220 Lift: 0.525 0.532 114 LSA
XR273HR 220/224 Lift: .530 .534 114 LSA
With that said ~.581 lift cam can go a long time, with a couple of valve spring changes, I have 127,000+ mile one my 224/224 XE-R .581 lift cam. There are better choices now that make more power and drive nice.
If I was doing a new cam I want at least a 224/230 and like I liked near stock mannered cars.
