88 YJ Fuel Injected 4.6L Rebuild

[RedJeepster]

Hey Guys,

Just graduated college and finally have funds to rebuild my stroker that didn't go so well when I built it in high school. Jeep is an 88 YJ that originally had the 4.2. Engine block for this engine is from an 87 Cherokee, crank and rods are out of an 84 CJ7, head, and all wiring and ecu is out of a 93 Wrangler. Pistons were new 0.030 over stock 4.0. Cam was from a 4.2 (my father made the assumption that the crank should match the cam) I built the original engine on the stand and swapped it in as well as switched to MPFI. Engine ran really well while it lived. Had to run high test gas because the compression ratio was so high with stock dish pistons. One of the wrist pins ended up freezing up and started to damage cylinder 3 after 2000 miles. That's when the engine got pulled back apart and has been apart since.

I am now at a point where I can start to look into rebuilding the engine. I would just like some advice to make sure everything looks kosher before I go ahead and spend a pile of money.

Going to start with honing the engine (I already have a hone from other engine builds) and see if the cylinder walls clean up. My father is a machinist so the cylinder walls will be thoroughly inspected before moving forward. If need be, the engine will be bored again to clean everything up.
Head is already decked (I believe .030, have to double check)
CNC dished 2229 pistons (have not yet determined how much dish will be needed)
Comp 68-231-4 cam
Bottom end will remain the same, reground 258 crank and rods, just an inspection
Felpro 26211 head gasket, compressed thickness of .040

What I am really not sure about is if I need to make any valve train modifications, and determining exactly how much I should dish my pistons. This Jeep will be a second vehicle and only really comes out in the summer and gets wheeled on the weekends.

Any input would be appreciated.
