This is a frame off build. We blew it down to every last nut and bolt.

VE pump Cummins set to 350 hp and 820 ft lbs of torque. All new bearings, seals, rings - ARP head studs, Cometic head gaskets, HE 351 Turbo, Aeromotive and Air Dog fuel management, Bosch 5x14 injectors, 60lb valve springs and a 4” exhaust. Pump was modified, timed and dyno’d by Diesels in BOW, NH. KDP done.

NV4500 - Trans was down to the case, blasted and painted, all new bearings and seals. Upgraded output shaft to manage the crazy nut.

NP205 - 29 spine input, 32 spline outs.

Chevy Dana 60 front - Detroit locker, 3.73 gears, all new bearings and seals. 35 spline all the way through

Corp 14B rear - 3.73s and a true track

We cut all the rot out of the body, sand blasted the frame, added 52” springs in front and 63” springs in the rear, along with a shackle flip. Paint is fresh, like everything else. Waiting to cut and buff it.

Interior is fresh, sitting around in boxes. Owner wanted the bow ties, not hard to change out. Seats are actual K5 along with the center console.
