Presume you mean the blue rear engined car - not Allan Cattle's blue front engined Volpini?

The rear engined blue FJ is Terry Collier's BMC Mk2 which Terry bought up from Wellington for it's first competitive outing. BMC stands for British Motor Car Distributors Limited from San Francisco and the car followed on from the Mk1 version which was front engined. The cars were built and designed by Joe Huffaker and are sometimes referred to as Huffaker-BMC. It is powered by a BMC A Series engine with a single DCOE 40 and a Volkswagen "Hewland"gearbox. It runs the original Huffaker-BMC cast wheels.
