Possible FSJ build, have some questions

I'm thinking about buying a later model Woody Wagoneer. I can't seem to track down my Cherokee. Here's some questions I have. It would be put together for a daily driver rig.

1st, I would want to make it 2wd. I would plan on using a rebuilt 700R4, and putting a straight axle in up front. Does anybody know where to get a straight axle of proper dimensions? Maybe there's one that came in a different rig that would bolt in?

2nd, Since I want to squeeze as much gas mileage out of it as possible, would headers and a fairly open exhaust be beneficial?

3rd, what intake manifold and carburetor would be recommended for optimum mileage?

I know these things are as aerodynamic as a cinder block, but I've been in love with FSJ's for a very long time. I know it seems outrageous, but would it be possible to get high teens (closer to 20) on the highway?

Your starting with a tough rig for mileage...stay away from the 401 - get one with a 360. Run narrow tires, you won't need to change the rear end gears with the R4. Leave the stock front axle and put manual hubs into it and unhook the driveline - non driving straight axle done! The older the Wago the better the mileage. The ones in the 80's were pretty mired down with smog equipment.

If you have more money - swap a Cummins 4BT from a bread van (4 cyl turbo diesel) and run a 4L60E with it - that's the standard set-up if you find the right bread van. I have a friend with this set-up in a 96 Suburban 4wd and he is getting around 21 MPG. Stock tires and wheels.

Good luck!

Hmm, good ideas. Some of the early wagons had a buick engine correct?

The 1968-1970 Wags might have had a Buick 350 in them but finding a nice one is near impossible.

Headers on a 360 are a good idea. Stay FAR away from Hedman's, Doug Thorley's are the way to go.

IIRC a CJ10 has the same front axle as a GW (maybe some wider - so narrowing might be in order) and it is a 2wd...

bj's offroad, my favorite jeep store. What about your part-time quadratrac kit, that's one way to get 2wd.
