I ordered a cam for my LS7 from Vengeance Racing that was marketed as 235/243 .657/.660 on "LXL exhaust lobe". I assumed "LXL" meant it was a Comp Cams lobe but when I received my cam I noticed it was manufactured by someone other than Comp. Vengeance informed me it was manufactured by CamMotion, which is fine, but can it still be an LXL lobe from a company other than Comp?

Sir if you do not wish to accept our word via email I would suggest contacting Cam Motion direct as I doubt many on here are familiar with either company's specific abilities.

I will also offer to exchange your camshaft for a cam cut by Comp Cams, but as mentioned in the email earlier today this will be on a different core material than the camshaft you currently have.

Feel free to email or call. We are happy to help any way we can.

Cam Motion can cut any lobe you want. Period. LXL itself may be custom to Comp, but the specs of the lobe are widely know... and Cam Motion can cut identical lobes on their superior cores.

Keep what you have.

Do not take offense to this post, my experience with Vengeance thus far has been a good one. I just know there's at least 3-5 guys on here that love to talk about cam profiles ect. Im not an expert but I do research a fair amount before I commit to something as important as a camshaft. With that said, I researched the Comp LXL lobe profile before choosing this cam, naturally I had questions when I realized the cam did not come from Comp. I don't think I said anything negative about any company here, just trying to take cam selection as seriously as possible before seeing 7k RPM on the back stretch at Watkins Glen!

The LXL lobes are proprietary to Comp, but that doesn't mean someone like Cam Motion can't duplicate the specs if they chose to.

No offense taken at all sir. As I said we are happy to help any way we can. If you prefer an actual Comp grind we can make that happen. Just let us know.

You would be a complete fool to trade a Cam Motion core for a Comp core.

Bam, all that needs to be said.

Pretty sure any talk of "trading" the cam did not come from me but thank you for your colorful comment.

I'm actually curious about this. Is CamMotion actually copying Comp Cams' lobe profiles? Or just copying duration and lobe lift?

Kip Fabre

We would Never copy someone else's lobes. There are none I have seen that we want to copy. We have our own designs .We will make any duration and lift the customer asks for but we will not give him the .006 and .200 numbers he wants unless it is going to be stable. Why make lobes that will be noisie and not RPM.

Thanks for clearing that up Kip. So the OP actually didn't get an LXL lobe. Just a cam with matching duration @ .050" and lobe lift numbers.

You're welcome.

Looks like Vengeance could update their website. It still says comp cams on some of the pages even though further down it gives the choices of 3 difference cam cores that Cam Motion offers.

Just out of curiosity. Why would the OP's Cam Motion cam exhaust lobe be identified as a LXL lobe if it isn't a Comp lobe?

Keep the Cam Motion cut camshaft with Kip's lobes (or possibly Vengeance lobes as Kip will make lobes for those that are dealers of his).

I have been nothing but absolutely pleased with Kip's camshaft's. He gave me a lot of advice and insight during the design phase of my new lobes and he has taught me a lot when it comes to actual velocity, acceleration and jerk and how they are manipulated.

Simply put, you will not be dissatisfied with the product you received from Vengeance if Kip ground it.

I dont think the question is if cam motions lobes are better or worse than comp. The question is if he specifically ordered lxl lobes, why didnt he get lxl lobes.

vengeance offered to switch it which is nice, you would hope they were just confused on what he wanted

Kip makes the easiest lobes on the valvetrain and they perform. That is a win win.

I would assume the lobe design you have from Cam Motion is very similar to the LXL lobe from Comp, but Kip would be able to answer that question in more depth and with great certainty. If it were me, I would just keep what you have, but Vengeance has given you the option to return the cam and have them cut the cam on a Comp core, using Comp lobes (i.e. LXL exhaust lobe).

A quick look and I found no Comp Cams nor Cam Motion patents on LXL. It is therefore a free for all name to use.

But I think we all know Comp has a nice inventory of lobes.
