what cam for this engine?

Hey all, we are putting together a 360. its a fairly low budget build. anyways its a .030 over 360
h405cp pistons, figure 8.5 to 1 compression

He also wanted to know what difference in power he would might see by going to a h116cp piston? It looks to bump the compression up almost another point.

He'll see about, at best, a 5% power increase with the higher compression pistons. I'd shoot for 9.5-1 for a ratio and any mild performance cam.
