    s52 cams

    Alright, how do you know if you have s52 cams or not? Sounds like a stupid question, but my boss pointed out something to me. How do you know that someone is not screwing you? The casting numbers are all the same between S52 and M52. Has anyone actually mic'd S52 and M52 cams? From what I have found, they are almost exactly identical. They have different lift and such, but I don't know how much lift I am looking for. Anyone know? or have any mic'd numbers? Thanks

    Valve lift on the S5x cams is 10.2 intake, ~9.7 exhaust. Since IIRC the rocker ratio of a hydraulic lifter motor is 1:1 you should have thereabouts 10mm difference between the diameter of the base circle and the peak of the lobe if it's an S52 cam. M52 cams are 9mm lift.
