97 tj with 4.2 stroker ??

SO a friend of mine threw a rod bearing in his 97 tj. It currently has a 4.0 bolted to an AX-15. He found a guy that had a 4.2 stroker for sale and bought it. The specs of the motor are listed below.

I am trying to figure out what it will take to make it work/fit, issues that I will run into, problems I will have.... Any insight would be great!

Engine Specs per the seller:

4.2L Base Block 258 block
Bored .040 over with Forged Dished Pistons
New Crank lightened, balanced, and polished
4.0 Head conversion

This is an awesome upgrade for anyone's jeep and will out perform most V8 conversion swaps
It is now a 264 cubic inch stroker with a 4.0 I6 head swap. Comes with a Header, intake manifold, injectors, fuel lines, throttle body, flywheel, clutch, ect. This is a direct swap in for any Jeep I6 and comes with everything. Why swap in a V8 out of a junk yard when you could put this in without modifying or changing anything while outperforming most V8's. I only ran it a few times until I sold my CJ. I pulled this motor out of it because I didn't get the amount of money I was asking for it so I pulled it and sold it with another stock 258.

Blue 93' YJ, 4.0, 5spd, skyjacker 4" lift, crager simulated beadlocks w/33" bfg muds, skyjacker swaybar disco's, dana 30/35 w/ 4:10's, skyjacker t-case drop, and many mods to do yet
