The truck is actually somewhat for sale too because we want to build a 12-valve highboy next. It started as a 1976 Camper Special with 52,000 original miles on body. This was a two-wheel drive C20 originally. Found a '94 Dodge Cummins 5 speed 4-wheel drive with 170,000 miles and took out the motor/tranny and installed into the '76 Chevy. The motor was honed and re-ringed with Mahle-Clevite rings. I had to fabricate motor mounts and frame crossovers. A few of the changes (many more basic things as well): valve job done on head, guides cleaned, new valve seals, new 60lb valve springs; ARP head studs; Killer dowel pin tab installed; new high flow performance injectors; remanufactured BD Diesel injector pump P7100; new 4000K governor springs; fuel plate ground to 0; new Southbend Single Disc Heavy Duty Clutch, flywheel and slave cylinder; 5th gear locking nut installed; Advance Adapter for NV4500 to Chevy NP205; new input shaft to tranny and adapter from Advance Adapters; Air Dog fuel system; aluminum radiator; Halogen headlights; straight piped. This truck is very nice looking and nice to drive. It drives like a newer truck and has plenty of power and gets around 18-22 mpg.
