I've been a fan of jeeps for a long time, but this is my first full size. I picked it up yesterday in fact so it is brand new to me. While I've wrenched a bit over the years I am no mechanic, I have done most of my own maintenance over the years but I've not done a lot of deep in motor work. The last time I fooled with carbs was on a '79 1 ton long bed club cab dodge with a 440 in it, sitting on 35" tires.
It appears to be a bit of a mismash of years. PO gave me a list of things that were done or changed. For example, the bottom end is from a '73 360, top is from an '89. He said an oil filter from an '89 is fine, but if I was to swap the starter it would need to fit a '73. Allegedly there are 5500 miles on the rebuild.
It runs pretty good, but it is a bit anemic in my opinion which I believe is related to the fact that he built the motor up but it's still using a 2bbl and stick intake even though he dropped a Performer-Plus cam in it. Runs smooth, idles well and hit highway speeds without hickup, cruise still works too. It sounds great because he put in a pro custom exhaust in, duals, the y is where the spare tire would be, so he routed safely around the fuel tank. Appears to be stainless steel. It is lifted and sits on some 35x12.50s right now.
It has the same problems that I've read about, slow windows or non-functional, I've got a lot of rust to fight, other than windows the electrical works right now that I've dropped a good battery in. The Interstate that he had was a good big battery but a check said it was bad. The volt meter would go all over the place when turning lights on or something. I put a Optima Red Top in it on the way home. Heat blows strong as did the AC.
I've got my work cut out for me on the rust side of things, and while it runs and idles well I think I need to swap in a 4bbl intake and carb. I was considering a Edelbrock 2131 and a 1406 carb. I've read that this is a decent combo. I also noticed some black soot on the snow, coming from the left exhaust when I dug on it a bit at idle. Is this a sign of something terrible?
Anyway, I've always wanted a FSJ, now I have one, but with seemingly a good bit of work to do.
Here she is along side my XJ.
