Roller Lifter Options for 59 deg R1 Block

Just to clarify, you ran the Crane Ultra pro rollers in a Mopar stock block with shaft oiling - no issues. Correct?


I have. I have never run pushrod oiling in my personal stuff. As a rule, as long as the wheel is .810 or bigger it should be a good lifter. Why after all these years Chrysler guys will buy junk that was slapped together with Chevrolet spec'd parts is beyond my ability to understand.
