Cams, do cams have any identifying marks? If not how do you know what you have?
 
thats a pretty good question.

The one's on my toyota have ID numbers on the front where the cam pulley mounts... But that's probably not helpful here.
 
Yes some of them do, and I've seen a list on the internet somewhere. Maybe Paul Tegler's site?
 
Hmm, only mark I can find is a "D" guess I won't know till I try to time it.
 
Jack, the cams , if factory, were marked in various ways. Some had part numbers on them, such as AEA 649. Some were marked with rings on the shaft itself. For instance, a cam with 3/8" wide lobes, and 2 rings would be a stock 1098 cam. A pin style oil pump drive, with 3/8" lobes and one ring would be an AEG 510, Cooper S cam. Check the lobe width, the oil pump drive style, and see if you can find any rings. I may be able to ID it for you from that information.
If you can't find anything, I guess the only altenative would be to send it to Crane or one of the other Cam companies, and have them run the profile for you.

Mine has 3/8 wide lobes and pin style oil pump. I don't see any "rings" but then maybe I don't know where to look?

The only thing I can find is a "D" stamped on the front end of the shaft.
 
Jack, the rings are on the unfinished portion of the cam itself, between two of the lobes. The part number, if it's there instead of the ring(s) would be in the same location.
If you do find a part number, that happens to begin with C, as in C-AEA-648, this would be a race cam. That particular number is the old standby 649 cam.
No rings, numbers, or any other marks would indicate a 2A 297 or a 2A 571. Stock cam in the early Mini and Bugeye.
Incidentally, I'm pulling this information from a combination of David Vizard's book, and the BMC Special Tuning Data sheets. I'm <u>really</u> not making it up as I go along! /ubbthreads/images/graemlins/grin.gif

Gona go look again, stand by.
 
No other marks, no rings, no nothing. Guess it must be stock.
