Engine 1984 CJ7 Engine Swap

I just bought a 1984 CJ7 2.5l 4 cyclinder jeep as a project. It has a new top end after the water pump died and blew the top end. It then was parked for 24 years and never used. I have not started it yet but was told this was the history with 166,000 miles on the rest of the motor. I am contemplating doing an engine swap and wanting to be judicious and not got crazy and want this to be as easy as possible. I also want to do this myself if I can for pride of ownership and would be the first time I have ever done anything like this. I am contemplating buying a 4.2l 6 cylinder crate motor. Does anyone have any recommendations about this choice and what I am going to have to replace other than a motor (obvious appropriate adapters) due to power increase (like transmission or transfer case, etc)?
