The business "Liberty Speed " which is owned by Brian McCosker commenced in 1975 as an Automotive and Mechanical Engineering Business. A short time later, in 1978 Brian ventured into boat racing - in the 6 Litre Injected class, sharing a boat with long time friend Mal McColl. The focus of the business was in Ski Racing, Lane Racing, Speedway, Motocross, and in general - building engines for all forms of motor sport and also for street registered cars.

After years of research and development with metals, heat transfer, swirl affects and flow, 1997 saw the release of the McCoy Cylinder Head which is built and machined specifically for the small block Chevrolet, yet utilises the technology of the Buick style symmetrical ports which eliminates the typical exhaust overheating in the middle cylinders which occurs on the Chevrolet with the 2 exhaust ports being side by side.

The business and boat racing have continued to grow and improve simultaneously with Brian now racing the very popular and successful Blown Alcohol Displacement Boat "Liberty", taking out all of the major Australian Races over the years and recently winning the inaugural World Cup.
