91 yj engine blown!

I have a 91 yj and the engine and tranny are going out... right now it has the 4 cyl... I can get a 4.0 6 cyl. engine with tranny for about $1,500... Can I just swap the engine and tranny right in or is this a hard swap considering the jeep stock is the 4 cyl??? Help please this is my first jeep.

It is very tough indeed. Nothing about it is just drop in. If you want to go bigger it is easier to go with a Chevy small block v8 than a jeep I6.

I agree, same amount of work and you have to change everything. might as well go big. kits for doing chevy swaps. and chevy parts are cheaper, easy to get.
