New cam break in procedure
I have not done a cam change in 10+ years. I remember back then someone told me the break in procedure was to rev it to ~2500 rpm for about 10-20 minutes after you get oil pressure. This was to ensure that the new cam got plently of oil.
Is this true?

Thank God for that! I thought I would have to do that with open headers. Putting in some LT at the same time.

Re: New cam break in procedure (ericcer)
I run the new cam break-in procedure with a roller cam anyway. I choose to in order to get all the cam lube and other contaminants circluating through the filter. I then change the oil after the 15-20 minutes running and really go break it in from there. ;)

Re: New cam break in procedure (Vette92)
I always run a new cam, even a roller, at 2000 rpm or so initially. This helps to ensure that the new cam lobes are getting a good spray of oil from the crank rotation. Higher crank speed more oil.
I also read an article in one of the car magizines that stated that you should not use breakin lube on the lobes of a roller cam. Just use oil. The reason given was that breakin lube is good for flat tappet cams since the lifter slides across the lobe and you don't want to chance a dry condition. But for a roller lifter you don't want the possibility of the roller sliding along the lobe instead of rolling across the lobe initially. This could damage the roller or the cam. Anyone ever heard this theory?
