Looking for a little more power out of a 318

A cam with a little lope is ground on a tighter centerline like a 110 or 108. Further down numericaly, the more chop to the cam. I have a Crane in mine on a 112. A slight chop to it and when fully warm, nearly gone. (That was the main idea)

I'd look at a split duration cam like around 224 intake degrees of duration. Look up a Comp XE series cam.
