Custom CNC Engine Builders for Street, Race, Offroad & Marine. Est. 1968.

We are engine builders with a primary focus on high-end LS and BBC engines. By “focus” we mean that we are well stocked with the parts required to produce our standard recipe builds from our own inventory. Parts availability translates to much shorter lead times for customer orders. We will also take on builds of other select American V8’s on a case-by-case basis depending largely on parts availability. Our shop has state-of-the-art CNC machinery and engine testing equipment. Operating and programming this complex and sophisticated equipment requires a highly trained staff. Our employees have benefitted from years of on & off-site training programs.

Our engines are purchased for their performance, reliability, durability and just plain good looks regardless of end use and whether naturally aspirated or boosted. The range of power adders we use includes twin screw and centrifugal superchargers, turbos and nitrous oxide. This provides an incredible range of power and performance options. Nearly all the engines we build are fuel injected and tuned on our dyno, but we also offer remote tuning services to our customers.

We work directly with a limited number of top-quality parts vendors. Our vendors have been carefully vetted, often with on-site visits to their manufacturing facilities such as shown in these videos. We have a strong preference for Made in the USA. Regardless of location, our suppliers need to demonstrate that their products, technology and service are going to help us put out the best possible engines as measured by performance, value, durability and reliability.

Among our ads, you will see everything from bare blocks and superchargers to representative complete engine builds that can be ordered and shipped to you. If you don’t see what you are looking for, please give us a call at 815-725-2727 or send an email to [email protected]
