Re: 4.2 rebuild
The engine is the original 258 in my 78, the manifolds have been replaced with those from an 83 for some reason that i could not even try to guess at. it has the pos carter on it that i have rebuilt. the engine starts right away and runs like a champ. it had 63k on it when i bought it and by the time (hopefully within the next two months) i get my 360 done and ready to go in it will probably have under 70k. the engine is pretty much bone stock, except it has the ford cap/rotor and is hooked up to an msd (which stays with the jeep for the 360). if you are still looking when i get ready to pull it i will let you know. everything comes with the engine except the alternator and the msd box (engine, head, manifolds, carb, smog pump, distributor, flywheel)
as far as your engine goes if the bearings are bad you may want to tear it down and see what else needs to be done. if the cylinders still look ok then you shouldn't have to bore it which will save you a bit of $$. PAW has kits for the 258 that include everything (all gaskets/seals, rings, bearings, timing chain, oil pump) for under $200 i believe.
