ok here it goes. I have an old '69 econoline sitting around. it has been sitting for about 5 years but my dad just gave me the go ahead to try to fix it up. I believe it to have a 351W engine in it. my dad told me the engine is pretty tired and doesent run very strong but still runs, and he mentioned somthing about one of the valves messing up but he just did a temporay fix kinda thing back when it was running. I will ask him tomorrow exactly what went wrong. now since this has been sitting I am going to flush the gas, oil, tranny fluid, and was thinking about doing diff fluid. am I missing anything? and what kinda prices am I looking at to replace the head and all the parts with one from pick and pull or somthing? thanks for the help guys.
