I have a Northstar engine out of a 99 sedan deville with "low mileage"(according to previous owner). It ran before removing from the car. I don't have any pictures here ( Its in storage about two hours north of my place) but could try to get a few pics from my buddy.
I was going to put it in my 48 plymouth, but opted for a more traditional engine. I'm not in a real hurry to sell, but make me an offer if you're interested.
