Well just wanted to say your pictures were an inspiration and you make it look easy. Im pretty excited to drive a stockish jeep again, my XJ was just getting out of hand for highway use.
Thanks! I had a good time with it, and I enjoy the smooth torque. The main reason that I bought the XJ that I did was the condition of the body. I can do mechanical stuff, but bodywork is an art for which I have little patience! To be honest, this was my first major engine overhaul that's actually running. I thought that an engine designed in the 60's couldn't be that complicated, and it's low-performance, high-endurance nature left a margin of error in which I could work comfortably. That, and being a Mopar/AMC guy, it felt like a good fit. It's only got 700 miles on it so far, but it runs great. It fired on the first try!

The complete machine shop bill came to $1,400. That included block reconditioning, crank polishing, and a complete rebuild of the head. I re-used the OEM valves, springs, keepers and locks. I learned that there are no replaceable valve seats on these engines. The valves seal against induction-hardened surfaced right on the head material. To bring the seats back up to where they should be, the old material had to be cut out, and new replaceable seats pressed in. That operation did cost a few dollars, but the head is a fresh as a daisy, and I don't have to worry about the grab-bag quality of mass-remanned heads. did the engine work.

That is a beaut if I ever did see. You really are an inspiration, if I had the know how to rebuild a motor, I would hands down do it as soon as I saw this.
