My dad had an older (70's) green F-100 with a 3 on the tree and that thing was a hot rod...he hadnt done much to it but it was pretty quick and it could get the tires chirping real easy! Now he HAD to get the benz...haha jk my mom made him get rid of the truck about 5 years ago so we got a 1990 F250 4x4 lifted on 35"s and its pretty sweet, it has a lot of power and it is pretty well muffled, but is mostly stock. That truck is dying though. Last week we drove it and we were going up a hill that it never has trouble on and it choked hardcore and the engine died. I took it out later and tried the hill later and it had no trouble, but this truck isnt in great shape anymore....time for a nice F-350 Powerstroke 4x4...
