Hi-Performance/Machine Shop Services

Standard machine shop jobs are available in many places. The success of specific high performance engine machining is co- dependent on many aspects of the entire package, and best left to the engine builder himself where possible. Many problems with performance engine projects have been traced to 'too many cooks in the kitchen, and no Master Chef.' Having one shop do your piston fitting, another your cylinder heads and cams, and yet someone else to do the assembling, is a recipe for unhappiness. J.C. Performance Engineering is your one-stop high performance shop.
