Most of you guys got me beat. I remember Scott's trip to Prudhoe Bay. What an achievement. Especially for such a good cause.
I have posted about this before. I had a 50 3600 with (probably) the original 216, SM-420 and 4.57 rear gears. See link in my signature. At the end of 2009 my family and I moved from Central IL to Fond du Lac, WI as I had changed jobs. We left the 50 in the care of a good friend of mine. It was May 2010 before we could go get it. We got to my friends house about 9:00 am. After a cursory once-over: check and top off oil, air up tires, put charger on battery for awhile - then took off. Almost 9 hours and 7 quarts of oil later, with a quite a few stops, we made the 320-330 mile trip. And man was it hot that day. My hands were sweating, and black from the old steering wheel got all over my hands. No break downs or problems other than the oil loss...
I would do it again.
