86 CJ7 258 w/ 4.0 top. D30

77 CJ7
80 CJ7
I picked up a 86 CJ7 over 8 years ago. The top end was swapped out with a 4.0l from a 96 Cherokee. When I got it ran find but it needed a new clutch and the Transmission plus Transfer Case got an overhaul. The Transfer Case had JB weld and if you can believe it… expanding foam
. Besides the crows nest of wires that went nowhere, the radio w/ amp had a switch but the wiring was so wrong 
. So after that and other wiring issues and ignition and radiator problems. Oh and there was a draw on the battery coming I think from the steering column…I had to halt the build. Now I want to start my spring list of what needs to be done to get it running. I do everything myself but most drivetrain stuff as I do everything in my driveway. Was thinking of just finding a drop-in swap and be done with it. Also money doesn’t grow on trees. 
ADVICE??!
