Resto-mods are some of the coolest builds out there, and there is no scarcity of men who will totally deck out an old-product auto or truck. Regardless of whether it be for pure nostalgia or aesthetic, they frequently transform out beautifully and remodel the primary into anything unbelievable. Such is the situation of David Pilgrim’s 1954 Chevrolet 3100 that we got to check out out at PRI final calendar year.

Pilgrim’s father initially bought the truck new the calendar year it entered manufacturing as a do the job truck, and drove it for all-around 20 yrs before passing it on to his son. It then saw use hauling for the Harley-Davidson dealership Pilgrim commenced and aided in his work in the Texas oil fields. By the late ’80s the Chevy entered storage for a few decades when Pilgrim commenced to focus on other facets of life. Racing experienced generally been a spouse and children enthusiasm nevertheless, and he knew he’d be saving it for later on.

David and his wife Debbie began wanting into drag racing following attending an NHRA function, which finally led to the pair coming into the Bonneville Salt Flats scene. Pursuing a couple of turbocharged motorcycle builds and a C5 Corvette that strike a most effective pace of 246.148 mph, he acquired the thought for the 3100.

The build started at Johnson’s Warm Rod Shop in Gadsden, AL, where the chassis was engineered to continue to keep the guidelines-expected factory frame rails underneath the cab. A number of other custom made touches make it possible for for the truck to be hyper competitive when still retaining its classic frame. The whole control pounds is someplace about 7,700 lbs. so that Pilgrim can get ample traction on the strip.

The most extraordinary component of the build is only that the 6.6L LBZ Duramax motor can fit in just the body of the truck at all. Originally, it touted a compact 235 cid straight-6. Now the smaller-frame truck not only has to residence a large diesel motor, but also an outstanding quad-turbo set up with sufficient piping to blow your brain.

“It’s generally all in the tune-up,” Pilgrim reported. “It’s a de-stroked motor with a Winberg crank constructed by Automotive Professionals Racing Engines in Concord, NC. It’s got Carrillo rods, Mahle 16.5:1 pistons, Edelbrock heads, and the intercoolers and rather substantially anything else is customized fabrication.”

Rick Squires and STS Turbo had been paramount in the quad-turbo setup that separates the develop from competitors. It is comprised of two sets of compound turbochargers that sit among the action-sides of the original long mattress. The 1st phase are Comp 62mm units, when the second stage is made up of Comp 72mm units.

“There’s 4 turbos and two intercoolers, a person in the entrance and 1 in the again,” he claims. “Air goes via the one in the back after the 1st turbos, then receives stepped on yet again and will come up front to get cooled.”

As for fueling, Pilgrim’s setup is supported by a number of S&S Diesel Motorsport goods that enhance performance, ability output and reliability. It has two big lengthy-stroke pumps alongside with 250{ca2182fc8fed51dc37b95061ee48b5056cde1176732b225548c54a0c0156d303} above injectors that function in conjunction with a Waterman raise pump.

Entirely, the LBZ can make a whopping 1,500 horsepower thanks to all the efficiency additions. That volume of energy was sufficient to propel Pilgrim and his 1954 Chevy to the land pace report in his course in 2021 with a speed of 220.226 mph.
