While unboxing all of the parts that came with my 1969 SRL I came across this :

Not sure how to ID the grind without miching it. I hate to remove it from the bag as it is sealed. It'd be great if it was a B cam .
No part numbers on box. Any ideas?

Look on the back end of it there will be either an "A" or a "B" stamped into it. Looks like a B cam to me, but hard to say without looking at the end of it.

As Will said look for B stamped on back end. For reference Competition manual says cam part number is 13000-25500

Not sure I need it. The car has a new B cam in the rebuilt head.

You'll have no trouble selling it if you decide to.
I'd bet a "real" B cam in factory wrapper would go pretty quickly.

I have no clue what the things worth. I'm sure it's not something you run across very often. If any one has any ideas. Let me know please. Thanks for all the help.

Dean sells a reground cam that's very near B specs and a new aftermarket cam that's even closer at something like $210 and $235 respectively. I think your new NOS B cam should easily find a buyer at $300. Since there would be no noticeable performance difference between your cams and Dean's cams, along with the fact that it's not a visible item, I don't feel there would be a substantial difference in value. Still a NOS B cam would be my choice over Dean's.

Im in the same camp as Mike. There is likely a bit of value in an original unopened box so Id guess he's about right.

Thanks guys. That at least gives me a fair idea of the value of the part. Likely it will be traded at some point for parts I need for my 69. Thanks again.

Except that, depending on how much the base circle is cut, you may have to use taller lash pads for a reground cam vs stock height pads on the NOS cam assuming the head is built right. Regardless, both will need new or reground rockers. Great find!
