They make good power, and I'm a former X-3 owner. I just think the FMS cams have a little more thought behind them and not just 2 XE-R lober stuck together with some advance built in. Any of us could do that.

Like i said, there is more thought put into the FMS cams. I still believe the FM13 would win in a low-end battle, all aspects being the same.

yours on 29 degrees of timing, low altitudes, 93 octane etc....
mine on 23-24 degres, high DA, 91 octane with MTBE etc... Your numbers will be SIGNIFICANTLY lower here. In Texas Lou consistently makes 440-450 rwhp in the Z06 cars with stock heads... but of course thats with 94 octane and real timing. Compare two like climates and I Think the G5X3s will come out on top. Im not ragging on the F13, I just feel Lous cam is superior here for my personal needs (And that of every customer of mine ive installed one in)

I am with Mike on this one personally since I own the cam and it works for me, but the F13 seems like a bad *** cam too, never seen on done here in AZ though. There is no way to compare these really, both make good power, but it's hard to get accurate results on a stupid dyno. You can have some jerk off mess with the dyno and you can make a million HP, but what counts is at the track, supposedly so far the fastest LS1 N/A stock cubes, etc etc, runs a G5X2 cam, what else can do you need. I am sure there are faster cars, but this cam performs. My car is not the best dyno car, and I wish it were so I can brag my *** off, but I know it will perform on the street/strip and that's what counts. I have seen a car that has 650 RWHP run a 13 at the track, driver sucks ***, but he has 650 RWHP The only way to see which cam is really better or makes more power is to dyno one, swap it out on the same car with the other cam, the same day, as fast as you can, then redyno it. Not gonna happen, so I guess be happy and choose wisely

Lots of people on this board have "custom cams" ground to there spec that are very similar to X3 specs, and they don't even know what the specs on the X3 are. So are they now cam wizards, or did they just decide on 2 XE-r lobes with a favorable split, add 4 degrees advance, and call it custom. You have your opinion and I have mine. Maybe we don't see eye to eye, but in a debate, who does? I like LG and FMS, but I lean more to one side. No need to take offense.

No, I don't think he got lucky. He came out with a cam that was bigger than everyone elses at the time. He advanced it 4 degrees to keep diriveability good and make monster low-end power. Is it a recipe for 4oo rwhp, sure. Maybe he paved the road for the bigger cam crowd. I wish the numbers were more repaetable than they have been. As for the X2 and 3, there the same cam. If you have something that works good, X2, lets just add 2 degrees of duration to it and call it something else and keep the specs secret. Lots of thought, or a good marketing ploy? You be the judge. I'm not going to bicker with you. I'll just keep grinding my own stuff, but wait, it has a foward split, xe-r lobes, and some advance, so I guess I'm just copying.

Oh now I'm copying? Other people, maybe, but I had cams with similar specs long before the X2 or 3 ever thought about coming out. The same specs, no, but similar. I'm starting to take offense cause it sounds like your saying every person who now comes out with a spec is copying. If he never came out with the X-series cams, mine would still look the same. I believe in a certain pattern and don't feel the need to have to mimick what others do. Once again, I'm no guru, but I have a pretty good idea of what works and dosen't.

Real quick question...how much are these cams going for? I can't find them on LG's site and have been told because he doesn't put them on the site. The Futral site is being updated so no prices there either. Also, on average, what are you looking at paying to get one of these installed?
TIA,
Justin

Wish I could say that was now, but I have many little things to attend to first. 
Thanks again,
