Be Careful. I installed that same cam a couple years ago and wiped number 2 intake lobe after bout an hour. Did the half hour at over 2000rpm thing. It appeared lifter was spinning too as the bottom of the lifter was a perfect bowl shape. Was using MP pre lube and Rotela oil with a full bottle of Redine Zinc additive. My bad, shoulda got better Oil. Went roller after that. If I did again, I would use a purpose made break in oil. The car was a blast to drive and sounded great with that .557 cam for the half hour I got to drive it. Had 509 before too... Also had a buddy in Boise who installed an MP cam in a small block and ran regular oil with no additive. It wiped every lobe. It was a mess. He didn't know about the change in the oil. He sure does now.
