Need Cam advice????
I am going into my motor and would like to know what cam to get. I have a honker, ghl bullets and american racing headers 1 3/4 w cats. I do drive this car on the street alot so I would like to have one that is best for the whole rpm range. I would rather just replace cam and not have to worry about replacing rockers, rods, etc etc. Any suggestions please? I do also have a tune in the car. Thanks in advance....

Suggestion
I've heard good things regarding Texas Speed's MS3 and (new) MS4 cams. They pull hard, sound great and are very streetable. Hardened pushrods and valve springs are required upgrades during their install however. They offer all these in a package. (I'm looking to do the same as well.) Are you leaving the stock cats?

Do a "cam" search here and more so on ls1tech.com. That site is loaded with valuable info and is crawling with gearheads who'll be able to help you out.
If/when you do this; be ready for the sound clip and dyno result requests! Good luck.

This was is easy, put in the battle tested street cam that makes huge power and has decent street manners with a good tune, that being the LGM G5X3 cam, that makes huge power on a stock headed LS6 motor and has been extremely popular with the Z06 crowd and other LS1/6 vehicles, the last 3 years or so.
You will need to buy a complete cam kit which includes hardened push rods, good dual springs good up to .650 lift, titanium retainers and locks. These G5X3 cam often appear for sale also in the for sale section and you can call LGM (tuner here) to get a ton more info on this killer cam. With headers and a tune you will make 425+rwhp with this cam and maintain your daily driver streetability (with your stock heads) and stock shortblock!!

I would stick with something in the low 230s or mid to high 220s. It sounds like for what you want and how you drive a cam in those ranges would be best for you.

Let me know if you want me to spec you one and if you are willing to change springs or not.

Good...I think a 220/224 or a 224/228 will work perfect for you if you want me to spec you one. The 224/230 114LSA cam that Comp keeps in their catalog would work good too, but it may not be quite as optimized and you will need some 918 valve springs to use it.

Also looking for a strong, midrange, streetable cam. Still trying to figure out what is best for me!

I recently wrapped up a G5-X2 install... I love it. FYI the first curve is my baseline for that day, not the pre-cam numbers. When I dyno'd in October at a buddy's shop the car made 376/374, which was down from 382/380 back when I had it tuned in January '06.
***Cobra4B's LGM G5-X2 Cam Install Thread***
The numbers are in... 424/378
Think a top end cam destroys your torque curve? Check out this comparison.

Pardon my ignorance but will this cam work with NO2?

Nice #'s Cobra!! I am looking at upgrading my current cam to a G5x3. Currently have a 228/228 .590 113, that with other mods, I'm at 450rwhp and 415tq. What I have noticed from reviewing the MS3 and MS4 dyno graphs, is they put down some big hp #'s, but are lacking on the torque #'s. I know all dynos are different, but compare 3 x3 cam only cars to 3 ms3 cam only cars, hp seems to be about the same, but the x3 cars have much more tq. Just my .02, but I am going with the x3 in my car and hope to be around 475-480hp 440ish tq!!

Notice the DCR is close to 8.5:1 for all these cams. This will maintain your low end power and keep your car from feeling like a dead fish under 3000 rpm yet is safe for 91 Octane fuel. I think you will find that all the "BIG Cams" that many recommend can't come close to a good DCR unless you raise static compression.

Swapping to upgraded valve springs is an ABSOLUTE MUST (or you will most likely grenade your motor) there is no way around it if you go with any of these aftermarket cams, unless you go with a baby cam similar to the stock Z06 and then it would not make any sense to do anything.
YOu also must swap to hardened pushrods and ALL most aftermarket perf. are offered as a complete cam kit with aftermarket valve springs and hardened push rods. YOu need to call a couple top notch tuners here and do a lot more homework so you can verify what I am telling you is accurate and you get the cam that is perfectly suited for you. FRom what I am hearing from you a cam with specs. with something similar to a 224/230, on a 114 lda and a .590 lift or so would suit your needs well. The G5X3 cam is a great choice as i stated above and so is the G5X2 that the other gentleman above references and posts a dyno graph with.
And to the gentleman about the N20 and the G5X3 cam, yes, this cam responds great both N/A and on the JUICE (N20)!!

Hammer - out of those cams you listed above, what kind of hp gains would you see on a 03 Z06 cam only with headers, honker air intake and a ported tb? They seem pretty mild compared to the big cams you see elsewhere; am I correct in assuming these would maintain good low speed drivability? Any dyno graphs of these cams?

I don't have dyno graphs...I could probably develop some virtual graphs in using dyno software. All those cams were designed based on desired Valve Events, DCR, and knowledge of how similar cams have performed. They will perform well, especially the LSK lobed ones if you are willing to use good dual springs.
