A FAMILY HERLOOM IS REBORN...

BENCHED P-PUMP AND AN S300

Turning Scheid’s injection shop loose on the P-pump meant that it could easily support a 500-rwhp effort, should Chris want to take things that far. The benched 12mm P7100 was graced with 4,000-rpm governor springs, larger delivery valves, a rack cap, and lives at 18-degrees of timing. It sends fuel to a set of 5x13 injectors, also built by Scheid. A 58mm Borgwarner S300G turbo matches the engine’s fueling and produces 35-psi of boost before the wastegate opens.

SPLITTING GEARS

Like a lot of 12-valve swaps, Chris sided with the rugged NV4500 manual transmission to back up the 5.9L, but in this particular case there’s a twist. A Gear Vendors overdrive allows him to split gears, which with nine forward gear options makes the truck much more efficient when tasked with moving heavy loads. A single disc towing clutch from South Bend, along with a solid mass flywheel, dwells inside a Quick Time bellhousing and transfers power to the rear Dana 80 (and also the front Dana 60 when the NP241 is locked in four-wheel drive).

A Gear Vendors overdrive unit allows Chris to split second through fifth gears, effectively giving him nine gears to choose from. The added gear ratios come in handy with a heavy load behind him, as they help keep the Cummins in the meat of its power band.
