mystery camshaft
I have searched and cannot identify a new camshaft that I have had for many years and lost the paperwork for it.
The number 975539 is stamped on one end of it with no other numbers. Does anyone by chance have a clue as to what this cam is...? Thanks |

Re: mystery camshaft
What engine is it for? Is it a GM cam or aftermarket?

Re: mystery camshaft
It is a sbc cam...don't know if GM or otherwise. This is what I am trying to establish. All I know is the number stamped on it and it has a red painted dot near the number And it is unused...

Re: mystery camshaft
Most aftermarket cams have the MFR's name stamped on it on the rear of the cam. Most GM cams don't have much info on them for identification. Is there a casting number somewhere between the lobes?

Re: mystery camshaft
Yes, the following stampings along the cam.
1579 between cam gear and adjacent lobe. Opposite this number is what looks like OWO. D6 is stamped b/t last journal and cam gear. B/t 1st and 2nd lobe is 117 or 11T. Opposite that is 25. No other markings. And thanks for your interest in helping to solve the puzzle.. |

Re: mystery camshaft
Yes, it seems like a crap shoot. Best I give up on this and focus on more body work so I can refit my cab to the chassis on my 62 stepper...!

Re: mystery camshaft
Not to be a wise guy, but that camshaft might be better used as a post for a mailbox. So much unknown, you could spend a lot of money and time for no useful result. The reason that I (jokingly) say mailbox post is because there is a mailbox at a house about 1/3 a mile from me that the owners actually are using a cam from (I think) a 6-cylinder engine for the post. I'll take a pic if you want, but a V-8 camshaft would be kind of short for that use.

Re: mystery camshaft
I may just consider that if I don't identify it. Thanks, good tip!
