v8 or 6 cyl with Dana 44?

I just picked up a 73' CJ5 with no engine, tranny, or t-case. In bringing it back to life I want to use the stock Dana 30 and Dana 44 axles, but I am not sure which is the best direction to head regarding engine/powertrain. I like the idea of a Ford 302/T18 combo; however, I am wondering if this may be a bit much for the stock axles (especially with lockers)? My other line of thought is to keep it simple and go with a later model 4.0L with a stock or common tranny/t-case combo. I would like to run 33's when I have it put together. Depending on tranny/t-case combo, I am wondering if I can keep the stock 3.73 diffs? or does stepping up to the 33's commit me to atleast 4.11's regardless of tranny/t-case?

This is my first jeep, and I'm looking to build a reliable rig that can hit some moderate trails. I feel I have a huge opportunity here given that I have "clean slate" to start with. Thanks for any constructive input.

pretty sure your dana 44 will be just fine might consider a 44 up front as well but he 302 and 18 combo sounds pretty good

I have the 304, T18a tranny and the dana 300 TC with the stock dana 30 and 44 axles w/lockers. The 3.73 with 33 would be okay, I have 35's and I went with 4.27 gears.ust didn't want to go up to the 4.56 due to the small pinion gear for the 30. But my set-up works pretty good. Hope that helps

Thanks for the feedback. Should I shy away from a solid locker, such as a Detroit? I figured I would address the 3.73 gears once I got it on the road to see how it felt in low range and where the speedometer tops out. Looking for a set-up that can pull 55 mph on the highway, not much more. I have a trailer for any longer trips.

Considering I have no tranny or t-case either, are there any advantages to going with a more recent 4.0, in terms of available parts, ease of install, etc.?

There will be more wires to figure out with a newer 4.0

I was thinking in terms of the mounting and/or fabrication required to support an engine/tranny conversion, vs installation of a newer "jeep" product. If both would require similar fabrication and/or conversion hardware, then I would lean towards the 302 conversion. If a 4.0 can be a simple "bolt in" installation project, then I might lean that way, knowing I would need to upgrade some wiring for the EFI.

i have detroit lockers in my jeep and in my '83 ford ranger pickup. love them! way quieter, smoother, and stronger than lockrights, powertrax, and similar lockers. well worth the extra money, imho.
