Here is another "advice on cam" thread!
Cam guy's.. I need a lil help choosing. I am wanting to put a cam in the car and I don't know what to go with. I don't know anything about a cam and I have never owned a cammed car. So I hoping to get some suggestions and input from you guys. The car is a daily driver and I don't have to worry about emissions. I would like good power throughout the power bad. I am wanting to put down 400 to the wheels with cam only. Currently I put down 326rwhp 365rwtq. The car is a '00 WS6 M6 and here are the mods: 6.0L, SLP Lid, SLP MAF, SLP Smooth Bellow, SLP 160 Thermostat, K & N Filter, Mac Performance Header System & Mac Y-Pipe, SLP Loudmouth Exhaust. Thank you in advance for any help/input!

Nice numbers given the mods that you have...that torque looks damn good. First of all, a lot in terms of camming your car will depend on whether you have an automatic or manual transmission. Driveability and idle is a little less of an issue with manual cars. Honestly, 400rwhp shouldn't be as hard to hit with 6.0L as compared to stock displacement, so there are a LOT of cams you could go with. Did you want low-end torque, strong midrange, or top end power? Very different applications that use very different cams. Offhand, I'd say to go with an FMS F13. It is a great cam for stock heads, makes great power throughout the RPM range, good power under the curve, and nice peak numbers. Or you could do what I did and go bigger than that. I have a fairly new cam, the TSP 233/239. While not a massive cam, it's still pretty big and makes nice torque on stock displacement (350+ rwtq above 3000 rpm), as well as nice peak numbers. Hopefully this helps a little, let me know what tranny you have and what you're looking for and I'll help you to the best of my ability.

The F13 consistently puts down over 400 on stock heads, especially on M6 cars, and definitely on am M6 with a 6.0. Should be around 415-420 I'm guessing. You could also look into a Thunder Racing TR230, TSP MS3, MTI X1 or Y1, or the time-tested G5X2/G5X3 cams. These are all excellent cams, and the TR230 and X1 are 'reverse split's with the intake duration larger than the exhaust, which works pretty well with stock heads. The MS3 is a BIG cam (237/242), the Y1 is pretty big (234/240), and the G5X3 is also a large cam (specs are classified). Any of these would get your over the 400 mark, with the larger cams putting you well over that. However, if you want your power to be more spread out, a big cam might not be the best choice. One more does come to mind though, the TSP Torquer. Simply an awesome cam, has put down 410+ rwhp on stock heads/stock c.i.d. and has over 300 lbs/ft at 2500 RPM. That may be a good choice as well.

thanks bull99ls1, what kind of power could i expect from the tsp 233/239 and the AFRs and every bolt you can do? Also can i keep the stock lifters but with roller rockers and new pushrods? longer pushrods?

2 Completely Different stories... Between N.O. & Blue00, there are 2 completely different sets of requirements.
There are NUMEROUS help guides with FAQS & tips out there. Use them. Absolutely no shame in doing a little homework. >After< you've read as much as possible, then start getting your head around what you want in a cam.
Basic: http://www.compcams.com/Technical/TimingTutorial/
A little more advanced (free download: right mouse click, etc, as intructed): http://www.motionsoftware.com/minigide.htm
Blue00: I'm gonna state an absolute: YOU CANNOT get to 400rwhp with a cam that is friendly to the *entire* rpm range and is suitable for a daily driver. To get 400rwhp (with just a cam) requires a lot of time w/ the valves open (valve overlap), which means HIGH, HIGH, HIGH rpms. I would suggest you find a local F-body group that has members w/ cammed cars. Listen and ride in those cars, if possible. Bound to be several groups around Dallas. Even though Houston is far away, call MTI www.motorsporttech.com They're very helpful. Also suggest you call the Comp Tech line www.compcams.com
N.O.: You aren't far from Clinton Township. http://www.automotiveperformance.net/ Your requirements are a little easier. Lots of power: Go 224/228 @112LSA. Nice lopey idle. Go Comp Extreme. Will need tuning. She'll run like a raped ape from 2500-6500rpms. Make sure you do all the necessary valvetrain strengthening upgrades.

I do several dozen runs a Summer at the strip, but mostly the ability to romp it on the freeway, stoplights and onramps is more important to me. A 233/239 needs some room. If yer spending lots more time at the strip than street, and will do ALL that is necessary to fully recover what that big of a cam can deliver, then go for it.
Lots of different opinions? luv2spd I was looking for 450- 500 at the wheels but want a good torque range. Maybe u cant have both? All i want is to run like a "raped ape" like ssinful said and put a spanking on my buddies (03 cobra w/pulley gears and intake) If a wider torque range lets say b/t 2500-6500 is faster or run better than a peak cam thats my route, but I want it to run!!!!!!
