Found a Mopar Performance cam #P4529188 no specs anybody know what it is? Anybody have a MP performance parts book late 80's early 90's

4589 = not that I remember/doesn't seem to compute.

4529 = maybe.

But....Struck out.
The 1989 catalog skips from P4529180 to P4529200.

(I also checked a couple engineering cheat sheets, and no luck with either p4589 or p4529)

That's not to say the number never existed. Just that it was never cataloged that I can find.

It wouldn't hurt to try 1990 and 1991 but I don't have them.

My next oldest one is 1998, and all I could find was P4529187 which is an oil filter/no help.

Neither '89 or '98 have P4589 so I just have to assume it's supposed to be P4529, but you can never tell.

I'm at the end of my rope....sorry.

Could be a development part that never was sold to the public. There are a lot of things like that out there.

It is a billet roller but none of the paperwork in the box match the number on the box and no cam card just a generic sheet with lots of cam numbers and specs but not this one. Shipping label on box says 1992 Thanks for your efforts

Yeah it really could have been in and then right back out of the catalog.

Maybe somebody has a 1991 or 1992 book to check. My collection skips those years.

Good luck in your quest.
