CJ 5 Engine Swap

I have a 1978 CJ5 with a 258 and a 3 speed transmission. The engine recently blew and I'm not quite sure what to do. I am going to do an engine swap, but i don't know what engine to go with. I was looking at either putting a remanufactured 258 in there or 304 v8 in there. My question is, will the 304 fit the transmission, and should i put 258 back in there?

A reman 258 will be the cheapest, easiest & quickest.
An AMC/Jeep 304, 360 or 401 is a direct bolt up to your T-150 trans.
If you opt for an AMC/Jep V8 swap, You will need every bolt on external part.
Not to mention the proper damper and flywheel.
Plus being from CA, It will also need to be smog legal.
