Not your normal cam question: Bearing journals.

Ok, a quick question. (Small Block)

My old cam (Crower Solid Roller) #2,3,4 journals were approximately 3/4" wide. #2 and 3 journals were fully grooved in the center.

My new cam (Lunati Solid Roller) #2,3,4 journals are approximately 9/16" wide. #2 and 3 journals have oiling holes.

I have verified that the number on the Lunati cam is the correct number. Voodoo Solid Roller Cam, P/N: 60432.


Is something wrong here or an I paranoid?
