1965 engine code decipher

And a bigger cam. (not by much) Lol
Oh? Well, There's the Real Change!
Does anyone have any Specs on the Two Cams used?
I have a 2-bbl non HiPo... Thinking about a Freshen up w/o changing the cam because there's too damn many of them!
It's gonna stay a stock Piston 2Bbl with Single Point and a Dual 2" Exhaust and 4-Speed (from 3-on-the-tree)
Idunno what the hell cam to choose for that other than the one that's in there?
