We invite you to take advantage of our small town atmosphere and open-door policy. At TOPP Performance Race Parts, we feel the racer deserves the opportunity to see his engine at any time, from machining and assembly to being fired up for the first time on one of our four dynamometers. Our winning tradition is based on customer satisfaction, not empty promises.

We invite you to take a look around our virtual tour and learn more about our products and services. Due to constant changes in our type of business, we encourage you to phone or email us for technical questions, parts shipments and price quotations on new complete engines, short blocks, machining, and components.
