Borowski Race Engines, Inc., Joliet, IL

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

We are engine builders with state-of-the-art CNC machinery and are market leaders in the field of high-end LS engines.

We marry our engines of all types with Whipple superchargers, Prochargers, Bullseye turbos and nitrous kits for an incredible range of power and performance options.

At first sight, we knew Dart’s LS Next® blocks would be a game changer as the differences relative to a factory LS block are visually obvious. We have been first in line for each new product variant introduced by Dart. The advantages of these blocks and the experience we have gained allows us to achieve incredible power with reliability. Our cutting edge LS engine technology has frequently been featured in Engine Labs magazine.

We focus on a limited number of top-quality parts vendors and maintain inventory of the key parts we use. This allows us to sell high-end parts, engines and assemblies on short lead times whereas other engine builders or parts suppliers may be waiting six months for back-ordered products. Our vendors have been carefully vetted, often with on-site visits such as shown in these videos shot at Callies and Bullseye. Our short list of manufacturers work closely with us and frequently provide us with their newest technology prior to market introduction.

In the ads below, you will see everything from bare blocks and supercharger assemblies to representative complete and fully dressed 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]
