1976 Chevy C10 - The Ultimate Swap
Classic Lines And 638 HP Of Diesel Power
About five years ago, Stefan Clapa took a ride in an 11-second Duramax pickup—a novelty back then. As soon as the pedal hit the floor, he knew he couldn’t get enough of it: the torque, the power, the diesel sound. However, Stefan was also a fan of old-school muscle, so he merged the two together and started working on developing a Duramax-powered Chevy C10 pickup. Fast-forward to today, and he is the proud owner of the truck you see on these pages.
The end result of all Stefan’s hard work is a vehicle that combines diesel power, classic lines, and street-rod smoothness. Without emissions to worry about, Stefan went nuts with power, upgrading the 6.6L LBZ Duramax with a host of aftermarket parts, including a Dual Fueler, GT4094 turbo kit, and Hot+2 E.T. Race tuner, all from Pacific Performance Engineering (PPE). Power comes in at a dyno-proven 638 rwhp and 1,280 lb-ft of torque and is transmitted to a Stage V Allison transmission, also built by PPE.
"I built the truck Ive always wanted!"
The actual swap work was the result of effort by Truck and Jeep Performance, PPE, and Stefan’s buddy, Octavian Vlagea. The engine was moved back 8 inches, the transmission tunnel was re-worked, and a custom hood was built. PPE supplied the computer and wiring to get the Duramax engine and Allison 1000 going. The final touch was a paintjob by Mobility Car Service in La Habra, California.
Now that the truck is done, and it’s been in the magazine, Stefan says he plans on putting as many miles on his diesel C10 as he can, visiting local car shows, drag races, or simply cruising down Highway 1 by the beach. With mileage approaching 30 mpg and more than 600 hp on tap in a 5,000-pound truck, he’s sure to have plenty of fun.
