Check out the video (above) of this LS7 with both nitrous spray bars and water methanol injection. This hydraulic roller R/T cruiser did an insane 1,429 hp on race fuel and nitrous. On pump gas with water-meth injection, it did 1,123 hp @ 6,800 rpm with peak torque of 995 lb-ft @ 5,200 rpm.

The fuel management system we used was a Holley Dominator which provides total control over power adders, timing, fuel flow etc. Plus and play at its best!

Price is for polished finish as shown. Also available in black. Serpentine system, water-meth, nitrous spray bars and Holley Dominator system are available at additional cost. Call us for a quote at 815-725-2727. Above Added: Wed October 12, 2016, 9:28 am EST


It just keeps getting better!

When Dart Machinery first came out with their LS Next blocks, we began marrying them with Whipples, the best-in-breed superchargers. Among other things, they are super-efficient at creating instantaneous boost for massive torque at low RPM.

One of the first group of Dart LS Next blocks got hooked up with a 4.0L Whipple and was featured in Engine Labs magazine. (see video below)

The 4.0L was able to run with a small pulley on race fuel for max boost and push out 1,155 hp at about 19 psi boost. Torque was over 1,000 ft-lbs from below 4,000 rpm all the way to 5,500 rpm. Switch to a larger pulley to dumb down for pump gas and it still kicked out 975 hp.

This 4.5L will push the boundaries further on boost and power. We can set you up with one in a variety of finishes while also offering custom serpentine systems for either wet and dry sumps. Better yet, we'll build your complete LS7 with one of these bad boys just as you like it. Please call to discuss at 815-725-2727. If you are down under, our Aussie numbers are 61-07-3040-0427 and 61-02-8011-3647.
