Jeep Strokers

Ok so I have been going back and forth with this. I currently have Nice 1998 jeep Cherokee 4.0 block that i havent sent to the machine shop yet but I'm wondering if I should pickup a 1999 block that uses the cam retainer instead of the bolt pin setup. Either way I'm going to run a stock camshaft in my 4.6 stroker. With all the camshaft problems I keep reading about I'm really leaning towards getting a 1999 block cause I can get one for around 60$ and then sell the 1998 block. Some other input would be great thanks

I don't think cam bearings are much of a problem with a stock cam shaft. I would just stick with what you have unless you really want the retainer plate setup (like I did). However you are limited to a single style timing chain and advancing or retarding the cam with offset crank keys.

I've been running the recessed cam bolt/spring/pin set-up in my stroker since Day 1, and I've done almost 70k miles on it since.

70k miles? Nice. Good build.

I'm past 72k miles now.

There is another easy way...Offset cam bushings are a cheap and quick route to advance or retard cam timing on just about any motor using a similar dowel alignment pin . They are cheap and plentiful from any performance parts supplier. All you have to do is drill the dowel hole in the cam sprocket to a specified diameter and slip it in....

Not for the retaining plate style I was referencing. It doesn't have a pin like that but a key cast into the cam gear. No pin to move a bushing around on.
