Anyone done this? Anything to look out for? I've pulled and replaced motors before (mostly small block Chevy's). Anything special or challenging about pulling one from an 05 Durango? Anything to look out for? The plan is to buy a complete engine from a junkyard minus ECU and wiring and just bolt it up in place of the existing one. There aren't any weird things with the computer that will prevent this are there?
