'86 Comanche Engine Swap

I am looking to swap out my 2.8l engine. It is starting to knock and I need to figure out the best swap for this engine. I know that the 3.4 is the easiest... but there are power issues and longevity issues with it.

I am planning on doing a complete swap, engine, trans, transfer if needed. I want to keep the front and rear axles for now.

I have seen multiple threads on many forums about swaps but there are issues raised about engines not fitting in the '86 but they fit in the '87 and later. I don't mind the work and can deal with the cost that will be incurred IF I know that everything will fit and will be compatible.

Any and all help would be greatly appreciated.
