About this episode

Heath Norton, president of Callies Performance, joins Kevin Byrd and Willie B to talk racing culture and how Callies has evolved from making crankshafts decades ago to offering multiple families of cranks, cams, rods, and even engine blocks. They cover why U.S.-made parts matter, how catastrophic failures and customer “autopsies” drive engineering improvements, and the company’s new Gen III Hemi aluminum block developed with partners like Direct Connection and Stellantis. Heath also weighs in on the return of horsepower wars, durability testing, and the future of performance as OEMs ramp up motorsports again.
