United Pacific to display ’66 C10 pickup with diesel crate engine


Scheduled for display at the 2019 SEMA Show in Las Vegas in early November is what is believed to be the first application of a Cummings R2.8 turbo-diesel crate engine in a street truck application, in a 1966 Chevrolet C10 pickup by Johny G. The truck is owned by Morgan Youngberg.

The truck will be showcased by United Pacific Industries, supplier of an expanded lineup of vintage Chevy C10 parts for hot rod and restoration projects.

“United Pacific is very excited to show Johny G’s latest C10 vision and share the growing enthusiasm for classic trucks,” Jai Baek, United Pacific marketing and creative director, was quoted in the news release. “It is a great example of what’s possible with imagination, creativity, attention to detail and the right parts for the build.”

The truck rides on a custom chassis, Bastille Concave U587 US Mags and Lexani tires. 

The short bed/big window body style was fabricated by Arizona-based Metalox Fab, which started with a rust-free, unrestored long bed/small window model but preserved most of the patina of the truck’s original green-and-white paint scheme.

United Pacific supplied LED lighting front and rear, door handles and window cranks, headlamp switches and the battery disconnect switch, among other parts.

The company also more new parts coming soon for classic C10s, including a short bed bedside panel for 1968-72 Chevy and GMC fleetside trucks, bed floor pan and tailgate (with the GMC script) for 1967-72 Chevy and GMC fleetside short bed trucks, and the company soon will offer a blank tailgate as well as a Chevrolet tailgate.

The new components are designed to help restore a factory short bed model or to make it easier to convert a long bed into the popular short bed body style.

“As vintage C10s continue to increase in popularity with enthusiasts, United Pacific is committed to developing more products to help them build the truck of their dreams,” said Baek.
