Ahhhh, I was forgetting about my tires. In that case you are probably closer to 5600. My '72 F-250 4x4 weighs @5400 and it only has 35's, and a front 44.
edt: the only thing aluminum on the 385 motor is the manifold.
My '75 F250 4x4 weighs in at 5600, has 390, dana 44f front end, 60 rear, 4speed. Only thing non stock is the aluminum wheels and 33's. OH, forgot I took of my boat anchors and put headers on.
