The Builder
A Machinist Who Builds Engines.
A Machinist Who Builds Engines.
Not an Assembler Who Machines Parts.
Craig Gerfen started at Alan Johnson Performance in 1998 working on top fuel and billet cylinder heads. He spent years mastering every aspect of engine assembly — balancing, decking, honing, block work, rod work — before founding Race Engine Systems in 2007. That foundation means complete quality control on every build, from raw components to the dyno sheet.
About Craig Gerfen
More Than Just an Engine
A Race Engine Is a System, Not a Parts List
RES maps the full combination — cam, heads, and short-block matched to your car and class — and can advise on fuel, ignition, and tuning so it runs right where it counts: in the car, not just on the dyno.
