dont know if your still looking for an engine but when i Hydrolocked a 3.8 on my last JK my insurance agency was the one that found one out of a salvage vehicle and sent it to the shop i had it towed to. May be worth asking them where they would look or even see if they would find one for you and then buy it. (somehow my insurance covered me to replace my engine so might also be worth asking if they will cover it under a comprehensive claim if you havent tried that already. USAA is awesome!! :rock
