The pink colour indicates to me it’s a Mopar Performance ‘purple shaft’ cam. Ryan Hill > On Feb 24, 2022, at 11:31 PM, D.C.

VR-1 racing oil might also be a good idea, it has zinc and can only help right? > > I can’t comment on the discoloration but do have an additional question for the group about the pink color on the shaft- is that a characteristic trademark of that brand of cam? Our project K has had some engine work done by the previous owner and we have no records, but it has a cam with pink on the shaft too (and even similar discoloration-see photo). I think the cam is fine. But Noel’s source sounds like a good one.

I had a bad exhaust leak and wanted to detail some things by taking the intakes were off. While apart, I wanted to look at the cam as I have never run zinc. The engine was assembled 20 years ago, using a Mopar Performance Cam P4452783 (6 pack specs which were close to the original cam specs). I degreed and retarded the cam per factory specs…. > > If the pictures come thru, the discoloration can be seen on some of the lobes. You cannot, however, feel any roughness or anything other than very smooth, even with finger nail. The lifters all still spin on the lobes also > > I am thinking since I am in this deep, I should replace the cam. Unfortunately, this cam has been discontinued and the replacement seems to be intergalactic backorder. I would consider a Comp Cams, but the specs are different. I’d like a lope to the engine, but when possible, I do drive this quite a bit around town and don’t have time to be changing plugs frequently, so I don’t want to go too large. > > My question is for those who have a lot of experience with cams and rebuilds.
