We have a 1975 F-350 and F-250. Both are 1975 trucks. The one with the plow has the 428 Engine and the black on has a believe is a 360, Brown has no power steering and the black one has power steering. Both are 4x4's and work. The brown truck as a up graded Dana 60 front axle and the black has a HD Dana 44. Trucks come with a hickey brush guard long out of production and transfer case skid plate. Have a extra four barrel intake manifold and a extra set of heads. Plow is a western big8' plow and does work. Brown truck has a windage pan and a high pressure oil pump. I put the lower compression heads on the engine so she would run with cheaper fuels. Truck has black jack headers and have a new spare set of blackjack headers for it. Tires on the brown truckare in very good shape. Planned to move the blackcab over to the brown truck as the body has some rust areas. Both Trucks have been sitting for some time butboth run
