Does the block need prep to run that cam?
No the Spartan Billet's are drop in camshafts that do not require journal bushings. But are required to only run the 60lb Cummins valve springs on the 12v's and only F1 Sportsman valve Springs on the 24v/CR engines.

Spartan has a special coating and needs the oil additive to work. Billet cam without coating is cheaper, but requires bushings machined in and installed. Both are really cool!
