I want to make clear that im only referancing flat tappet cams. I know nothing about running a big nice roller cam in a Cummins and could defantely see room for a big improvement there. There is Night and Day diff. in my huge flat tappet grinds [+.650"] that Ive ran in years past vers todays Big solid roller grinds that I run in my sbc race engines. Thought Id mention that... but I do believe 90% of the cam threads that people here are talking about is the old fence post flat tappets.
