351C! That was a nice engine. I had a one of those in a '73 Mustang. Right after I got it I was doing about 40 one night and had my right rear wheel pass me, take a right turn across three other lanes of traffic and stop neatly in a parking spot at the Circle K. It had sheared off the studs and dropped onto the brake drum after the wheel departed. Cut a nice groove in the road, but drove nicely. Pulled into a parking lot, threw the wheel in the trunk, and walked home. Small town so no point in trying to do anything with it until morning.
