This 1,990cc BMW M10 inline-four was built for racing by UK specialist Lester Owen and later installed in a Chevron B16 race car. It was overhauled in 2019, used for approximately 13 hours, and features high-compression pistons, Arrow connecting rods, dry-sump lubrication, and dual Weber 45 DCOE carburetors. A January 2019 dyno sheet indicates peak output of 234 horsepower at 8,000 rpm.
