    I guess it was about 3 years ago that I installed a Comp cam. Slathered it with break in lube, filled it with Rotella T5 10W30 and a bottle of ZDDP Plus, and then drove it that way all summer. Still running fine.

        Bought a .557 purple shaft solid with lifters,several years ago, broke it in recently with the inners removed, and a mix of old racing oil (new, but lots of zinc) diesel oil, and lucas breakin additive. No problems.
        I would NOT buy the purple shaft again, however. Their prices have gone absolutely insane. I think i paid under $200 for cam and lifters, now almost $500?
        Next cam i buy will be a solid lunati.

          yeah what happened with that (pricing)?

          comp has a series that are reproductions of purple cams; specs online for both seem pretty close

          Not necessarily recommending Comp, just if somebody wants a purple cam it’s pretty close and not cost an arm and a leg

          And today’s purple shaft is not yesterday’s purple shaft - they changed the grinds a few years ago. AND, they’re not even purple anymore.

          Im guessing the old specs must be out there and you could always get a custom grind to match.

          Very true; just didn’t want someone read that they are close, when Comps HP version isn’t

          I think Crane has one with specs like the HP cam but need to check

          I got the .474” in ‘96; had to pass smog test then; cam specs then look the same as now.

          Then may have changed the actual grind some, which might affect performance; am interested if that info is around

          5 posts since within a 12 hour period? You're certainly doing real good at that aren't you? :blah::blah::blah::blah::blah:

            TBH, I was just thinking that myself and was feeling kinda bad about it

            But now that you mention it, all of it was responses

            I haven’t posted anything unprompted and so am actually pretty inline with my intend to quiet down

            Thanks for helping me see that

            Search the forum for posts with titles that include “wiped” and variations of “destroyed cam”

            Only 3 hits over ~ 10 years

            Figured there would be more...

              I liked the 2330 cam, 2 different 440 challengers about 17 years ago or so, with the stock 906 heads and “six pack” pistons they sure made good power.

                I think if this question was asked 15 years ago when they first dumped the zddp (and people didn’t know it) the hit rate of wiped cams would be much higher. Most have learned now and the problem is less frequent.

                    I had that same thing happen last Summer. Comp Cams with unmachined edges on several lobes sharp enough to cut my leathery skin.

                      so after reading this thread I am again unsure as to which brand is is best, or safest. I am finishing my 69 383 Cuda, and I want a cam that won't crap on me, and be as close as possible to the original. In other words I want the roadrunner cam, not the 330hp cam. bottom line is want to do this only once. I lost a comp cam 10 years ago, and it was a lot of work to redo the 383 in my Charger. Hughes sounds hi quality VS some Issues with other brands?
