318 replacement cams....

Like most things with poor low end, what is the timing profile?

A 318 with an xe268 should run really well.

Overlap does nothing for CR. The overlap numbers you are getting from the hughes site are misleading. They are .050 lift numbers.

Ooops, yeah it was at 50 lift. From their site:
