S. Jennings Racing, LLC has extensive experience in rebuilding engines from virtually every decade of racing. We have produced engines for everything from an antique 1930’s MG to Porsche 993 cup cars. Utilizing state-of-the-art research and development techniques, we pride ourselves on our continual pursuit of the best racing package available. Upon arrival, all engines are disassembled, cleaned, and evaluated in a meticulous fashion using such processes as magnaflux, pressure testing, and precision inspection equipment. All assembly and rebuild processes such as main line and cylinder honing, rod reconditioning, and complete cylinder head services are performed in-house. Should the need arise for a component that is no longer in production, our full CNC machining capabilities allow us to manufacture custom parts within our facility, focusing on quality control and exact replication. All engines are run through a break-in and tuning process on either of our two water brake dynamometers utilizing the latest Depac data acquisition software.
