Probably not the response your looking for but..

Consider the cost of the injectors ( $200??) + tune ($200??) + will you be happy with it? ($$$$ >> ?????)

I get quite a few Jeep guys asking if the 4200 drive train will fit... A few years ago I did a quick test fit into a TJ and the 4200 engine, 4l60 + xfer case fits, I would think it would fit into a Cherokee as its longer.

In stock form the early 4200 make 275hp the later ones 290HP

With a little bit of head work this jumps by 30+ HP.

Quite a few people are adding a turbo to a bone stock 4200 engine and getting 400 RWHP with a tune ( to keep the engine alive as they are 10.2:1 CR).

Something to consider.
