At the 2022 Ultimate Callout Challenge, the Exergy booth had a Z28 Camaro parked in front. The car caught out attention, but our interest was piqued when we noticed it was a twin-turbo Duramax engine and not a gas engine sitting in the engine bay. We spoke to Lavon Miller of Firepunk Diesel, the shop behind the build, to get the run down of this Duramax-powered Caramo.
