We made a profit doing my son's head swap.
Bought a complete motor and trans from a '93 Cherokee donor for $300.
Took the ECU and wiring harness from the donor Cherokee.
Pulled the head with intake and exhaust including the fuel injection stuff off the engine.
Took the head off the 4.2, sold it for $75 om Craigslist.
Sold the AX15 for $250 on Craigslist.
Sold the lower half of the 4.0 for $150 on Craigslist.
Gave the carb to a friend.
Gave the AC compressor to another friend.
Had to buy a head gasket, intake/exhaust gasket, valve cover gasket, oil, anti-freeze, gasket material for the mechanical fuel pump home made cover plate, serpentine belt, and a bone yard gas tank with fuel pump for $27 from a '95 YJ.
The thing runs like a scalded dog. It has way more power than my stock 4.2 does. It starts easier, does not stall on a steep hill, and does not bog out on the freeway going up inclines.
We ended up taking the entire Jeep apart, sanding and primering, had a friend come paint it, and put it all back together. It's nice now...
