5.9l magnum swap questions

I would locate an LKQ in your area. They only warrant known good running engines. That means there is less of a chance you will run into something cracked. I think they warranty the engine as a whole and if you disassemble it, you void the warranty.

Big whoop. If it was runnin good, you will probably not have anything cracked. I got my 1999 5.0 Explorer engine for the RobKat for 300 bucks. It had a 6 month warranty, because it was a good running engine. I tore it down and it was super clean on the inside. It was so clean I redid the heads myself and put some good springs on, and reassembled the engine with new rings and bearings. Never saw the machine shop.

You will be money ahead doing the same thing.
