The 2022 SEMA Show is in full swing, and like every year, there’s a heap of manufacturers, distributors, retailers, restorers, builders, race teams, and more packed into the Las Vegas Convention Center in an effort to unveil some of the latest offerings in the specialty equipment industry. As always, there’s also a ton of decked-out cars and trucks on the show floor for attendees to drool over. And where there’s show vehicles, there’s bound to be some impressive engines.

We found today’s Diesel of the Week last month, but it’s currently sitting at the DUB Publishing booth #84320 on the SEMA Show floor. Dustin Sterling’s 1972 Chevrolet C10 is a showstopper; the fully steel truck is almost entirely factory restored outside of the panels and cut-down ’07 Chevrolet 2500 4WD chassis.

“This really is a dream truck of mine,” says Dustin Sterling. “I’ve been wanting to build something like this for years and now it’s finally come together.”


Dustin is the owner of Sterling Diesel Performance, a Splendora, TX-based shop that does everything from basic repairs and fleet services to performance upgrades and custom one-off builds. The new 7,500 sq.-ft. facility maintains 7-8 trucks at any given time with another 20-40 outside on the lot, all supported by 12 employees who Sterling says are almost all family.

While the team works on Dodge, Chevy and Ford vehicles, Duramax engines have become that platform they specialize in. Likewise, each iteration of Sterling’s personal ’06 Chevrolet race truck has given himself and the team at SDP a better understanding of what works and what doesn’t. For the C10, Sterling chose to use the same powerplant and many of the same component additions as his race truck.

“Texas is probably the biggest 4WD scene out there, so there’s a lot of classes that we can fit into with a truck like the C10 versus our race truck, which is very stripped down,” Sterling says. “This is going to be a street/strip truck, so we can do the 5.90 or 6.0 index while still being able to mess around with it on the street.”
