Had a guy give me an 86 w350. It has been sitting long enough for the tires to rot off of it. No rust, but someone has put spacers on the rear and changed it to single wheel. Question, what is the length of a shortbed? I want to make this a one ton Shortbed. 360 is gone and it has a 440 or 383. Not sure yet will find out tomorrow when I drag it home.
