the 2.5L only has 85hp and a max speed of near 73mph in the CJ7. im obviously going to regear to 4.88 gears when i put on the 35's but will i even be able to drive this thing on the freeway? (speed limit is 70 here) i paid 1k for this. haven't put hardly anything into it but even after i get it all set up the way i want i don't want a trailer queen. nor do i really wanna swap the engine and trans right off the bat. im just wondering if i should resale this and try to find one with the 4.2L or possibly a different jeep.

70mph + 4:88's = 3300RPM. For any amount of real 70 MPH distance driving on a regular basis a 2.5 will not live long with that setup. My oldest CJ has 4:88's/35's and 60MPH (2800 RPM) is about tops for cruising any real distances. And that's with a balanced V6 EFI engine pushing well over 200HP.

Find a rather cheap/plentiful 360 AMC & T176 to put in front of the 300 case, then some 4:27 gears. That will give you 70 MPH and stay together around 2800 RPM.

Short of buying a $20k+ Collins Bros. Jeep, most CJs on the market are pretty much 10 owner basket cases or WAY over priced.
Decide what your end goal is, get a good base vehicle for that goal, keep it, work toward the goal bit by bit.
