Wow. This needs updated. I had my timing jump which snowballed into killing my starter and about five teeth ripped off of the flywheel. Since the motor is starting to have blow by again, I decided to do a 4.0 swap. Located a 4.0/aw4 combo from a 98 XJ and dragged it home. Then went and pulled a full harness with ecu and trans controller from a different 98 XJ.

Also started to disassemble the stuff on the 4.2. Still need to buy a bunch of parts and send the harness off to get thinned out and made to mate the CJ to the 4.0. Fun times ahead.

always wanted a cj8. cant wait to see it with the 4.0

Not as big of a project today. I took out my old (1996?) suction cup mount phone holder and installed a RAM mount using a screw in ball replacing one of the dash bolts. So far I like it a lot.

Painted my motor, head and valve cover AMC Blue

You going to run the 4.2 Intake with the holley sniper setup, or convert to the multi port 4.0 EFI?

Already sold the sniper and the offy intake from the dead 4.2. Going to use the multiport injection for the 4.0.

Cool! How’d you like it? I’m trying to determine if worth added costs for self learning vs the standard TBI like Howell or Affordable Fuel Injection offer.

I loved my sniper. The thing was dead on reliable and no cold start issues or warming up needed. It had two little issues, which are well known. I had to reset the idle air control by covering it and setting the idle. This was needed to keep from having a super high idle. Took 5 minutes max. The other was the fact that the linkage for the throttle cable connection is not high enough to get enough leverage so you get horrible throttle tip in. I added a flat piece of metal with 2 holes in it to raise the mounting point 1/2 an inch. Solved it. But Holley sells a progressive link for $12. They should just include it in the kit.

But again, I loved the sniper and would do it again.

Were you using the timing control too? Holley has the dual sync distributor to allow for easy timing control

Lookin good Dain! I've always loved AMC Blue, then again, I've been playing with AMC's since I was 11...

Thanks. I can’t wait to get this thing assembled and in the Jeep again. And yeah, I am partial to this color too.

Well, no turning back now. Removed the manyal pedal box and installed the auto pedal box. What a pain in the arse. 2.5 hours but it felt like 8. Had to remove the fuse box and drop the steering wheel as low as possible to get the old box out. And ask me why I cleaned and painted the new pedal box? No clue. No one will see it.

While my buddy is honing the cylinders of the new motor and putting it all together, I bought some 35s off of him.

They look to be more than just 2” bigger than the current ones.

Looks like the 35s are on either a 10 or 12” wide wheel vs 8” for your 33s?

My 33s are on a 7” wheel. I think the new rims are either 10 or 12. Not sure as I have not measured them yet. But definitely a wider wheel.

Kind of swapped a transmission (and cash) for these YJ uppers that will work with my hard top. Not the season for them, but I am not driving the jeep right now anyway. The soft uppers are TJ uppers with the rear pin cut off
