87 YJ Build

Hello all, Im new to this forum and just wanted to share what I am planning here. My father recently passed away, and I inherited his 1987 Wrangler with the inline-6 4.2. He and I completely rebuilt this engine over a decade ago, and in the process I learned the basics of working on vehicles. The engine still runs great today, but a few years back the Peugeot BA tranny seized up. It also has some body damage and a few disconcerting rust spots in the body tub. My plan is to get this jeep up and in good running condition again, and continue invest in this project over the years as a testament to my father. It's something I can always remember him by, and I can use all the knowledge he gave me along the way. First step is to find a good transmission and get her rolling again. Probably going to spend the extra and find a rebuilt NV3550. Then I will assess the condition of the body and see if it makes more sense to replace or repair the damage. In the long term Im thinking of eventually doing a full coil spring conversion (and probably dumping way too much money into other various modifications along the way). Now as far as the powerplant, I know that the 4.2 was not the best engine ever put in a Jeep, but for sentimental reasons it must stay. Im looking for solutions to get more power out of the 289 though, and solve some of the carburetor issues that plague it. Please give me your thoughts, and I will try to get some photos up here at some point. Thanks!

First off sorry for your loss but at least you have some good memories with your dad.

As far as carb changes if the carter carb is working great for you leave it alone it rarely if ever is working fine so if it is bad you can try cleaning it or rip it out and put in something different. I messed with my carter for six months then dumped it for a motor craft am very happy with it but I did get one with venturi's that are to big so be careful on that.

Fix the rust soon in my opinion I do not like to see that sit old Navy welder in me.

More advice will be forth coming for sure from other members.

Sorry for the lost of your Father.

As for as the old Jeep goes if your planning that much work and $$$$ just replace All rust, body, frame and every thing, when it starts to rust it hard to stop. Do some reading on here to see what others have done, and use there knowledge to help along. and as for as that old six, if stock it's a 258 and a lot can be done. If your changing every thing else build a Stroker out of it, it'll have the same crank shaft [The Heart and Soul] of the Old Motor.
