The way I read that, He is selling Only the engine, and listed the information about the van so You could detail the engine specs.
I really doubt he is selling a entire van with free shipping for 1745$
If this is the case of only the engine with 132k miles. thats NOT a very good deal.
He also doesnt state if its a long block or complete pull out WITH trans.
IF it was a complete harnes, engine, ECU and trans, Then and only then would 1700$ be worth it a that milage, and thats hoping for a 4L80 attached.
Also still kinda high on the price considering the milage and the "unknown state of the engine and or trans".
You need to ask some detailed questions and find out what your getting before you buy a shortblock or some crap for 1700$
Be very careful here
