Services
Ray Bonthron began working on and racing cars at a young age, helping his father who owned a gas station and convenience store. Ray worked on his friend's cars along with his 1970 Boss 429 Mustang which he began to drag race in 1974. He also owned a 1970 Boss 302 Mustang, which he bought as a road race car, and switched it to a street car before switching back to a road race car.
Cylinder heads can help generate power but can also help lose power. It's all in the details. Our Serdi 100 machine and Serdi HP cutters combine to give you the best possible valve seat job available. The cutter contains 11 individual angles across a smooth radius. And with valve angles ranging between 30 and 55 degrees, we can help you pick the best for your heads.
Whether sorting out small issues, tuning for more power or simply making sure your car is performing at its optimal level, a dyno is the only way to properly tune your vehicle's engine. Our in-house SuperFlow 902 engine dyno is the perfect way to break-in a new engine, tune for optimal power and make sure it's problem free before going into the car.
Engines, the heart of every car, deserve the best. With more than 45 years of engine building experience, we have seen it all. We tailor each build to the needs of the application to ensure it functions the way it should. Our services range from rebuilding your current engine to creating one-off racing engines.
Quality, not quantity is a key factor in our vehicle restorations. Everything, except for paint, is done in-house and overseen by two people. This allows us to monitor quality control and ensure each build meets our personal standards. Whether a race car, custom build or show car, we can assist with getting your project completed.
