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? Here it is.  Check out the video below featuring this same long block in a C7 Vette running a single 94mm turbo:

This is a custom build based on a common foundation of parts we try to keep in stock. In this manner, we can deliver and engine built for you quickly. That is a rare thing in this time of supply chain disruption.  Because it is a custom build, this price is indicative.  The actual price may be higher or lower depending upon your choices.

The short block starts with a Dart SHP Pro LS Next block and our precision CNC finish machining. The rotating assembly combines a Callies' Magnum center counter-weighted crank with their Ultra I-beam rods topped with custom Diamond pistons. The crank's 4 inch stroke yields 427 cubic inches displacement. Both wet and dry sump systems are available with dry sump preferred.  A GM F-Body oil pan is standard but the correct wet sump pan will be chosen to your vehicle needs. A Dailey 6-Stage dry sump however is the best choice to lubricate your engine and turbos under the full range of conditions.

We strengthen and stabilize the valve train with COMP BSR shaft rockers. All Pro cylinder heads with our CNC porting and valve job machining provide unrivaled strength and performance.

Our custom billet intake manifold comes standard in a black anodized finish.  Its low profile allows it to fit under a C7 Corvette hood and is it a looker!

We have a range of other great intake manifold options available such as the purely functional elbow intake to the automotive jewelry of the included billet low-rise intake. A Holley Hi-Ram with built in liquid-to-air intercooler is a great choice for running gasoline. Talking about fuels, we can provide 16 injector designs to give wide flexibility in fuels with tunes and fuel injectors to match.

The 76mm Bullseye NLX turbos are full ball bearing designs - no thrust bearings, no journal bearings. The patented high-efficiency compressor blade design and tuneable compressor cover cannot be copied by Bullseye's competitors. Did I mention these turbos are manufactured in the USA?  You are encouraged to watch the videos down below for more detailed information on parts and machining.

The standard engine management system is built around a FuelTech 550.  These units are built for motorsports.  The powerful ECU and data logging is integrated into the waterproof display. The wire harness is far more robust than the typical sportsman grade harness.  Besides having a great product line, FuelTech is famous for its customer support.
