G5X3 vs Comp XER
I am ready to purchase either the G5X3 on 114 or the Comp XER 238/242 on 114. Because LG will not disclose their cam specs I was wondering if there is any difference between the two cams in driveability, HP and torque settings on a stock 02 Z06 other than LG headers and Random Cats. Someone told me they are pretty much the same cam but I would like more opinions. I will also be purchasing the dual valves, moly push rods, titanium retainers, etc., etc. I priced LG's package price of $1295.00 for parts only and that seems a little high compared to the Comp individual part purchase.

The quick answer is of course there is going to be a difference in hp/tq. It is a different cam. There is a reason that LGM doesn't disclose their specs, just because you get a cam that is "close to" the specs of a certain cam doesn't mean that they will perform the same.
With that said you might luck out and get something that works just as well or a little better even, but what if it turns out to be a turd? Then all the $ you just saved by trying to go with a generic cam went out the window. If you want a G5X-3 then buy a G5X-3 and be done with it.

I suggest contacting Al at LAPD (there's probably a link here somewhere). I recently was looking at a '02 Z06 they recently did a head/cam job on and this car produced 478 RWHP(!) That's almost 40 rwhp more than most other tuners have been achieving and that's a lot.
I believe they have the best combo of AFR heads, Com Cam XER cam, FAST intake, headers, and programming available right now based on these dyno numbers. Just my.02.

I would not say LAPD is getting more then most. Alot of them are getting 460-490 from their H/C with an aggressive cam AFR's and FAST intakes.

Far as solid numbers and drivability, all the big dogs in the valley here have X2 or X3 cams, and we have an incredible tuner so all the cars drive like stock... we just did a X3 114 in a 98 C5 with 96,000 miles and an auto and the car drives FLAWLESS! He is on the board as well if you would like to talk to him more

470rwhp from an ECS install of AFR heads, G5X3 cam, and FAST intake (and that dyno was done with 4.10 gears 
).

It's never made sense to me that someone would buy a cam without knowing the specs. I'm sure it's worked out fine for lots of people who don't care as long as it works. I mean not being able to know if you can go to 1.75 rockers, or what other spring options you might have, or what if you want to install it yourself, how would you degree it in without knowing the IC? etc, etc.
Honestly if th CompCam solution is close, and probably cheaper, it would be the way to go IMHO

I'll make one last comment...you get what you pay for. Though the "turn-key" LG G5X3 cam kit may cost more, it includes the BEST of everything components,
I would argue that the G5X3, considered to be a "big" cam, when installed with all of these components and professionally tuned produces excellent results, as measured by HP gains and retention of great driveability characterisitcs. 
Plain and simple...great cam technology, with scores of satisfied customers as referrals.

I couldn't be happier.. See sig. My numbers are with stock LS6 intake, stock mufflers, and stock water pump.
I sure I could hit 490 to 500 rear wheel horepower with 90mm LSX intake, electric water pump, and terminator mufflers.

I think the cam your looking at is bigger than the X3. I think it is around 232 242 or some where in there. Its a comp XER grind any ways. Everythinks it is some big badass developed cam. ITS JUST ANOTHER COMP CAM!

FWIW..I've been through this process myself. After doing my due diligence on many cams and their grind and manufacture origin ...most of the time the source is a major grinder like Comp Cams.
Yes, many of the popular tuners will stamp their name on a particular grind and Yes, they may even design the grind but my research tells me that most all of the aftermarket cams come from one or maybe two sources..Comp Cams
I am now running a Comp Cam 240/244-608/612-114 on my baby 382 LS1 stroker and am really very happy with it. I've been through 3 cams. from mild to wild and they all came from one source regardless of what the name it said on the box....Comp Cams!
..Just my .02 but that's the fact! ..Good Luck
