I looked at a prospective farm truck a couple days ago. 98 Ford 350 dually single cab standard transmission. Body in good shape inside of the bed is dented up on the wheel wells. 300K miles so it will probably need an engine soon. The main problem I had with it was the brakes and clutch. You literally had to stand on the brakes to get it to stop (very stiff). The clutch wold not fully disengage. You had to grind it into gear but once in gear you could let out on the clutch and go. Any ideas on the brakes?? I am sure a new pressure plate and disc wold fix the clutch. What is the going rate to install an engine. Would I be better off overhauling the original engine?? He is asking $3500.00
