318 (275 Hp)

The Mopar grinds are 30 years old single pattern cams more ment for the track rather than the street.
Single pattern cams work well with heavy ported heads.
Split pattern cams help squeeze out a few RPM and HP. This is due to the extra exhaust duration. You can have to much exhaust duration. This is why there generally limited in the amount. Cranes have more exhaust duration and work ratherly well with stock or mildly preped heads.

I also agree with post #18. I know what you mean. The last year has been rotten for me. Last few months have been unbelieveably bad.
