318 Build on the cheap

That slug reminds me of a stock slug minus the part numbers stamped in it. When I did my 318 build up, I just cleaned the top of the pistons. Same texture and rings and hle in the center. Just no part number.

I can not I.D. the cam other than it is a purple cam.

If you can figure out your exact comp. ratio, then a better cam (If possible) can be selected. To much cam on a low comp. ratio'd engine won't be the greatest thing off the line. You could probably get away wih the cam you mentioned.
