Oddly enough, Brett Deutsch’s Chevy C10 started its life as a diesel very early—before the Duramax engine was even invented. Originally owned by Brett’s grandfather, the ’69 Chevy had a three-cylinder Detroit Diesel two-stroke that was swapped in. It was different and unique, and Brett’s grandfather drove it as often as possible and entered various parades to show off his creation. Brett always admired the truck, and when he turned 15 in 1998, his grandfather surprised him by handing him the keys. Brett was now the proud owner of a diesel-powered C10 pickup.
But there was a problem for the Elburn, Illinois, native: rust. Luckily, Brett and his father Don were the hands-on types, and they swapped cabs, found a step-side bed off a ’95 Chevy, completely restored the frame, and painted the truck gloss black—all in less than a year. After the truck itself was restored, Brett got the go-fast bug and swapped in a 350ci small-block Chevy, then later a 383. Two superchargers and three blown engines later, Brett decided to go back to the truck’s diesel past, so he sold his gas drivetrain and used the money to purchase a Workhorse bus chassis that had been outfitted with a Duramax/Allison combo.
