baseline gmc halfton. Its still in the garage getting a complete over haul. Tilt front end and suicide doors are in the works right now. The 4.3 will be built from the ground up with forged .030 over pistons, forged rods, chromemoly push rods, comp cams camshaft kit, twin turbos, and other goodies. Transmission will be changed to a 5 speed or if i go with my original plan of irs, it will get a 6 speed manual and torque tube setup from a c5 corvette.
