8-12 is expected.

On a 1973 some parts are harder to come by than 74 and up rigs. A 1973 has drum brakes in the front, some of the interior gauges are the same as 74 and up so not everything is all that bad.

Are there any engine swaps that can help out in the fuel economy

Yes there are. A throttle body will help too.
Don't let the mpg discourage you to much....see the "coolness factor"!

Already got the coolness factor and a 10mpg factor covered in my weekend warrior, was looking to make the j series truck as my dd and take the place of my 87 wagoneer which gets about 20 mpg which isn't great by most peoples standard but it rocks my world of 10 mpg on premium, sorry another question, I'm a young buck sitting on my 26th year of existance and was wondering if the 73 had ac, didn't know if that creature comfort was avalable in 73 for the j series

J truck takes the coolness factor to another level.
What do you have in the waggy that gets 20mpg? "not great by most peoples standard"...just about any Jeeper would kill for that kind of efficiency! My '06 LJ doesn't come close.

Nothing special a 4.0 renix that I blew up, just put a ho 4.0 in, still working out some bugs in the swap but I'm hoping I get similar mpg out of it, I'd say 90% of my driving is on the highway if that explains my mpg

He is talking about the baby waggy.....A properly running stock XJ can get 20mpg easily.. your driving style just has to be the correct one.

You could do something like this diesel that originally came from a FSJ frame (Yes, its mine. Shameless plug.):

Low-mile CJ-10a Nissan SD-33 I-6 diesel and 727 trans - *$1200, limited time!* - Great Lakes 4x4. The largest offroad forum in the Midwest
