The last few used engines I bought I got a little sloppy keeping track of my cams. I know its a small block roller cam and I'm pretty sure this one was a 48 degree dirt track grind. Here are some numbers off the end.

4141
308-5
2775
B6552
488A
R9

Any help would be greatly appreciated.


2nd question

Do slightly used (1) or slightly damaged ( 1 or 2 ) billet roller cams from the late 1970's early 1980's have any value?
these were the often used R286 Duration 750 lift cams common back then
