Are you looking for a truly extraordinary engine for your ride? Do you want incredible power, cutting edge technology, top-shelf parts and want it now? Want plug and play? Look no further.  The engine in the photos and videos was featured by Dart at the 2016 PRI and written up by LSX Magazine in an article entitled Borowski Race Engines’ 1,540 HP 427 Dart LS Next At PRI 2016 .  Technology and parts availability have changed since then and so has our recipe.  The net result is that the current version is even stronger and more capable than the original as seen in the video below.

We can build this engine to run the fuel or fuels of your choice. As shown in the video, our break-in tune yielded an awesome 1,540 horsepower with two 76mm Bullseye TCT turbos on race fuel.  1,800 hp is the limit for how far to push the hydraulic roller lifters before moving up to mechanical lifters.  Using the included Holley engine management system, boost can be easily dialed back to suit a pump gas tune for street.  We did the tuning on our engine dyno and provide the tunes for your fuel combination with the engine.  The self-learning Holley Terminator X will adapt and adjust after installation as it learns your vehicle and driving conditions.

Let's talk big-ticket performance parts. The foundation is the recently introduced Dart iron LS Next SHP Pro block that we upgraded with 1/2" head bolts and our precision finish machining.  This block has the same high-nickel metallurgy as the original LS Next but is fully skirted and able to accept OE accessory drives, oil pan and oil filter.  The engine will come a GM oil pan to fit your already LS equipped vehicle.  You can also get the optional Holley retrofit oil pan for LS swaps or a Dailey dry sump oiling system if you are planning for some serious motoring.  The rotating assembly combines Callies' Magnum center counterweighted crank and Ultra rods with Diamond pistons to provide a 4 inch stroke and 427 cubic inches displacement. All Pro heads with our CNC porting and valve job machining let this bad boy breathe.  Another new feature is the COMP BSR shaft rockers which do great job stabilizing the valve train. The new crankshaft is a major upgrade over the one in the original engine.  Check out the videos below to see why we like the Callies' Magnum center counterweighted crank and All Pro heads so much.

We have replaced the elbow intake and are now offer a range of intake manifolds to suit your needs and taste.  The standard choice is a Holley Hi-Ram which will accept the optional 417 Motorsports liquid to air intercooler. This may be exchanged for a FAST polymer intake in either the regular or high-rise configurations.  An optional billet low rise intake is also available.

Our top-of-the-line serpentine serpentine system features AC, PS and a 225 amp alternator to keep all your electronics going. The power steering pump can be ordered with the fittings to accommodate a Hydratech braking system with remote reservoir.  If you are tight on space, we also offer the Holley Premium mid-rise bracket-less accessory drive.

The standard finish is black for the engine, accessory drive and intake manifold.  Polished finishes are available for all these components as well as for the turbos.  This is a piece that not only delivers the wish list, it looks great too!

Here are some great add-ons to consider:

• Upgrading to the Terminator X-Max for electronic trans-control and drive-by-wire capability.
• Adding a fully customizable Holley Digital Dash to replace or augment your instrument panel.
• Ordering a paired transmission kit.
