Well, it's a Comp Cam, but I can't find that lobe profile anywhere in their (online) master catalog. http://www.compcams.com/Technical/Ca...terCatalog.pdf If you scroll down to the last pages of the catalog, they have all their lobes listed in a lobe index. Yours (2870) should be listed on page 162, but isn't. I do know (for a fact) that they have lobe profiles that aren't listed in their catalog. I'd give them a call, I'm sure they'll be able to help you.

If it's in good shape and you intend to use it or sell it the best bet is to send it to someone for a Cam Dr report.

Are there any other markings on it at all?

I googled pretty heavy and didn't come up with anything but this thread

here's an idea, grab a sheet of tracing paper and put over that area of the cam and use a piece of black chalk and trace over the areas that are scribed on the cam and see if if you're able to get more lettering out of it.

edit-do it top and bottom because I barely see some lettering on the bottom portion of the cam.

If I had to guess. I'm going 240/240 .588/.588. 2870h seems to be the core I've seen it from many cam vendors and the only Ls hydraulic roller lobe comp offers that ends with 53 is the specs I just listed.

Fst100-Thanks for the help fellas ..bit no luck on the paper and black chalk.

Fst100-Yes I can read the top letter in but the bottom it has numbers that I can't even identify. So that's what I was asking for help on.

Tug686spd-im gonna just find a place here in Houston to get it measured .
