The auction is over for the SRT-6 motor and tranny, and it only brought 1k again. Which didn't meet its reserve.
I asked my Nephew about it, and he said once a part goes on EBAY, the only way you can buy it is thru their EBAY sales division.
He couldn't tell me what their reserve was, and this is only me speculating, but they may be receptive to a bid of $2,500 to $3,000.
I don't think the engine came out of a flood car, because LKQ is either one of, or the largest salvage vehicle companies in the Nation, and they have a very good reputation with body shops and insurance companies everywhere. So I don't think they would risk losing their good image just to dump a bad motor on somebody.
I purchased a Magnum V8 and tranny from them a few years ago and it was just like it rolled out of the factory. I wound up not using it, but the guy I sold it to, put it in his Dodge Dakota pick-up and was running low 14's with it stock. He told me it actually ran better than the one that came from the factory.
