318 with 4 bbl setup. 4 speed manual transmission, with low rear end gears. The 4x4 works great, This truck will pull great. Has a really nice 9 ft dually flat bed with tool boxes. Recently new starter, clutch, and edelbrock carburetor. Does run and drive, but needs small brake work and throw out bearing. Still a lot of good in this truck but don't want to mess with it anymore. As is.
