Engine tear down

I tore down my engine this morning and wanted to post up some numbers and maybe get some info. Everything looks consistent with what the PO had told me. The engine should have about 25k on it since rebuild but since I am doing a frame off, I decided to tear it down and go through it. There was no ridge at all on the cylinder walls, the pistons slid right out. He said it was a 69 302 from an Econoline van, this is what I've got:

Block - C80E-6015-A
Heads - C9TE
Intake - C8AE-8426E

The pistons are TRW's and 0.030 over, the crank was turned and mains are 0.020 under and rod journals are 0.010 under.

He said he had put a mild cam in it. The only numbers I could find on it are:

E951P - on the end
CWC and a EP15? cast into the shaft between a lobe and bearing journal.

Do these cam numbers mean anything to anyone? Is there any other way to tell what I have here for a cam? Thanks!!

The C being the first character in the casting numbers indicates 60's era parts. I don't know anything about the cam. If you can't find any info on it it's not that expensive to put a new one in with the specs you want. Then you'll know for sure what you have.

Yea, I drove the Bronco for 7 years before I started the frame off. The engine is basically stock, 2bbl, stock heads, but with this cam and headers. It does make pretty good power.
