I can understand why they wont release the specs. The G5X3 is a regrind of a Certain Comp Cam, so if people knew the specs they might just buy the Comp Cam and take it to a machine shop and BAMM they have a G5X3 cam. Some people might already have the CompCam and if they knew the specs would just regrind their cam. So I can understand why, thats why I just bought One and am trusting them on the PVC clearence, but I also can understand for guys with strokers or milled heads, those guys need to know the specs.

A lot of guys have experimented with less radical lobes on the exhaust side. It seems to do well and help valvetrain stability.

And to whoever said it costs $100 to maket he cam......I guarantee you that it costs LG more than $100 to make one of those. The R&D and knowledgeable customer support of a great company like that is what you are paying for.

Its been said 100000000 times, if it bothers you that much, then dont buy it and quit bitching about it. Its that simple.

Cam blanks are cheap and all the grinding is done by a cnc grinder so there is very little cost. You can buy a S.B. chev cam for around a 100 to 200 bucks, about the same size for raw material, same time to grind AND some one did the R&D. I have been in sales on and off for 30 years now, and there is a saying when it comes to pricing" what ever the market will bear" I just like paying a fair price. Sorry if I afended any one, its just a cam.

The specs (I know both specs) are very close to what many vendors have used for 4 years.
There is nothing magical about them except they are good cams that work.

Edit - theres nothing wrong with the Trex, or thunders cams, just stating that if everyone knew the specs and copied the cams, then everyone would have one... EVERYONE has a 224 or 229 or 230 split cam, even if all from different companies and they all make the same results... those who want the bigger numbers turn to the ones NOT everyone has, IE Trex, G5X2/3 etc... but there is a lot more to a cam then just tossing huge grind numbers on the table and having it built... look how terrible driving a MMS 229 cam was when they first came out... you would think the cam was a super stroker cam with its characteristics... obviously later versions got better, but what im getting at is the technology in the cams like Lous are what makes them a great cam and a better purchase than the next guys...

It is a standard split (6-8 degree exhaust duration bias) cam with duration numbers similar to many off the shelf grinds out there.
I think it is a great cam and performs well but it isn't some radical grind that hasn't been tried before with success.

That was also done in a car that was VERY lightweight with great driving and a well setup combo. (suspension, gearing, weight etc etc)
The bone stock internal record is in the 11.2 range.
I am not arguing that it is not a good cam. I am just saying it isn't radical as far as cam designs go for a small block V8.

but you could take off the shelf XE-R lobes on a 112LSA and make numbers identical to a X-3 112...granted you know the two duration specs...you wouldnt be able to tell the difference. Valve events are valve events...regardless of who grinds them. If they are similar, the engine will perform similarly. A major factor in how a big cam will idle is how radical the lobes are. The MMS229 cam had old slow lobes. Fast lobes yield less overlap. And I'm not doubting that Lou has helped the LS1 community go faster...he definitely has, but his cams are not splashed with holy water when they're shipped out.

Lots of folks want something for nothing, in this case they want cam specs.
Lets ask ourselves another honest question. If you had the specs @ .050 what would you do with them. Would you know what you were looking at? Are you going to compare them to another similar cam and say "Well, this one is bigger, so it must be better." ?
Now, for those of you who actually understand what a cam is, and what it does. Who can actually use a degree wheel, etc... please apologize for my comments if they offend you I'm trying to make a point here.
I don't necessarily agree with Lou's policies, but I understand why he does what he does. My biggest gripe with any of it would be if I were an installer, and it didn't come with valve evetns so I could check them. But, I know most folks follow the tried and true "dot to dot" method. I prefer to check things a bit more though, (but what do I know...).
Anyhow, instead of guessing at Lou's specs why not just randomly pull lobes out of the comp catalog and start making your own cams....
Here , here are the XE-R lobes, have at it...
