Custom CNC Engine Builders for Street, Race, Restoration & Marine. Est. 1968.
Our suite of state-of-the-art CNC machinery is the most advanced available. The staff boasts
more than 100 years of collective experience and includes accomplished racers and crew chiefs. Using only quality parts from reliable manufacturers, this combination of machinery and experience means that your engine will have more horsepower and reliability.
We are not your usual cookie cutter, generic engine-in-a-box guys, but rather a full custom shop. We will restore any American muscle engine to stock(but way better than factory), build to your spec up 4,000 hp all out race motors, and anything in between. Our builds cover the full spectrum of power adder and fuel options.
Dart Machinery has long been our preferred block supplier. In our opinion, their recently introduced LSNext® line is a game changer and the differences relative to a factory LS block are visually obvious. The bottom end strength has allowed us to push the envelope for more power and reliability. It has also opened the door for us to marry these with Whipple superchargers for an incredible range of power and performance options that will fit underneath your hood. We chose Whipple because their advanced twin screw design offers the highest efficiency, incredible instantaneous torque increases at low RPM and thanks to its vacuum actuated bypass, naturally aspirated gas mileage at cruise conditions.
This cutting edge technology has been featured in Engine Labs magazine, first as naturally aspirated build and subsequently supercharged.
Our HellFire® line of semi-custom engines are built to order on short lead times from inventoried components. 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@example.com
