The casting markings are located so you can see them when installed - but there are so many marks, I don't know if you can make sense of it all. Here are Chrysler mini-van cams - there are more marks than what you can see in the pictures:

One cam is marked in various places with 22/1/A/K/F. The other is marked with B/F/K/20/3.

"K" sounds like it could be the designation for Chrysler, but I'm not sure.

If you know what to look for, I guess you can figure it out. I think I'd want a Montero cam for comparison.

Note that if the block contains the 10:1 pistons, it's probably an interference engine - so be careful.
