Wow.........sorry to hear about this misfortune. This is the second time someone on the board hit a deer in less than two weeks.
Since I'm right in the middle of doing a head gasket on this SD, I have visions of a newer engine in it. But, the effort is a bit more than I could do at this point.
I concur with Snibble. It is worth $1K to the right buyer. But, you may need to wait for them. Most of those engines go for less at a junkyard, but, the risk is more. You need a smart buyer. People on this board.
Shipping is the biggest issue and is normally the deal breaker. It might cost $400 to ship it half way across the country.
