Note on original posting: bottom end rebuilt with new crank, etc. Comes with receipts. This is not a junkyard motor but presently running in a car. 

You might get these confused with motors sold by a certain SoCal vendor. Supposedly low miles and good condition. 7 out of 17 were DOA. One particularly pretty one I saved for myself had suck up a valve. Supposedly has 48K miles and pre-tested. Ha! Nothing like being able to drive and compression test your donor.
