What is a good cam for my LS3
I am wanting ideas from you guys out there that may have changed your camshaft. My C6 LS3 is a manual 6 speed with Z51 kit, it is stock except for a tune and is getting headers [2""7/8] when the cam goes in. I dont really want to change the thottle body as I have been told it should be big enought. 95mm.
I want a cam that has rough idle :within reason: but will still pull from 2500-6500
What cam do you guys suggest. PS I live in New Zealand but that is no barrior as we get things from USA all the time. Thanks Ross

I loved the Spinmonster in my car. It made awesome power NA and also made great power once it was boosted. I was 501whp with the cam, headers and ported intake. 695whp with my V3 Si at 9psi and drove great. Just search for Spinmonster on here, you can get all the info on the specs of the camshaft.

I hope you meant to write 1 7/8" headers. Anything over that would be nothing but taking away from the engine. Also, the oem throttle is 90mm.
My recommendation to you is to talk to one of the known shops to come up with a custom cam based on your expectations. I went with Martin@Tick Performance. You won't regret it.

Another vote for the Spinmonster cam. Makes about 500 rwhp on an LS3 with supporting mods. Another option would be to contact Patrick G. For $25 he will spec out a cam to suit your needs.

I went with a PatG/EPS custom cam.
2009 LS3 M6 base
230/238 .629/.629 112+3 Cam
Longtubes/full exhaust
Drag radials
STOCK intake, STOCK throttle body
Netted me consistent 128mph+ trap speeds.

I just got a Brian Tooley Racing Stage IV cam (233/248 .619"/.595" 113+5) put in along with a 10% under drive ati super damper, BTR .660 valvespring kit, comp trunion kit, halltech intake, pfadt 1 3/4" long tubes WITH cats and put down 490. Great drivability, lots of power, great idle. Couldn't recommend it enough. Brian is a great guy to deal with an answered all my questions and concerns quickly.

Is your car an M6? Who did the tuning for you? Have you run it at a track as yet? If so, how did it run?

Don't have a digital of the sheet, just asked for one. Here is a video of the dyno, you can see the plot at the end.

480rwtq!? damn! I was expecting to see some low torque numbers. Those pfadt headers must have done the trick. Do you have full length 3" exhaust or it goes down to 2.5" at the axle back? Those are some impressive numbers and it looks like you got the right color too
#15
Daaymn! That's awesome. I think I've found the cam I want! I have the pfadt headers and MF103 too, and I'm going to throw a high stall converter in it soon.
Beautiful car by the way! Love that blue with the gray rims

It looks like 480 is the HP number from the last run and torque is at 442ftlbs on the 490hp run. Still, that's pretty damn impressive and it sounds beastly. Sounds like it has a centri on it.

Yea the final numbers were 490 hp and 442 lb-ft, the last run actually shows up as the middle set of numbers. The car has good usable torque everywhere. It's not a full 3" exhaust, it goes down to a 2.5". I really like the BTR stage IV cam, and Brian is a great guy to work with. I wouldn't hesitate recommending this setup to anyone.

What about this cam?
http://www.summitracing.com/int/part...8-11/overview/
From the specs, this seems like it would be a good all around cam for a stock headed N/A LS3:
- decent intake duration - 227* @.050" (good enough for > 450rwhp?)
- 8 degrees of split int/exh which is healthy but not too big (most of the LS3 grinds have huge splits (>10*)which some experts like Spinmonster say creates too much overlap)
- 113 * of LSA which should mean good torque production in an N/A application
- just over .600" lift which is where the stock LS3 head seems to stall on a flow bench.
And it's a Comp grind, so it should be good quality, and it's a decent price to boot...

To answer you post, those specs seem good enough on paper. Those lsl lobes are quite aggressive. Meaning that your valvetrain is going to be noisy and take a beating too.
Once again, you have the opportunity to talk to a vendor and get exactly what you need. The cam part of an engine build should not be guessed.
