Well some interesting developments over the weekend!! I was hanging out with a buddy of mine who is a drag racing junky and is getting burnt out from it. He is getting into guns now.
He has an Gen3 LM7 5.3L vortex engine with ARP everything. Gen4 internals (thicker connecting rods, etc) and he figured the engine alone (for me) is worth about $700-$900.
Well I have built a few ARs and my 5.56 that I don't really shoot... Ever. I figure it's worth about 800 bucks or so.
We started talking and we traded him built motor for my AR truck gun.
So I went to the wrecking yard and picked a complete engine/trans harness, ecm, factory fuse block and MAF sensor for $40.65.
After a few hours of stripping tape, loom and pulling unneeded circuits from the harness:
I removed: All emissions related circuits, all A/C circuits, the complete transmission circuits, removed the rear heated O2 sensors, low oil level warning circuit.
I did leave a few random circuits like the 4WD low, tachometer, electric fan relay GROUND (switched ground by the pcm), I added a second circuit to the pcm for the high speed electric Taurus fan I have had installed for a few years. That will also switch ground at the high speed relay.
Doing some wiring repair on the crank sensor relay, the wrecking yard torched the converter bolts out through the flexplate and that three wire circuit was burned through the insulation. Its pretty cold outside and with the approval of the wife, and help from an old undersized bedsheet I'm in the house repairing that circuit and wrapping the harness in woven polyester tape (this is the same tape I use at work for harnesses, high temp and high adhesion.)
