- 800 HP, 427 ci Aluminum Hydraulic-Roller LS Engine for Road and Track
Description:
Here's an engine that can do it all for the weekend warrior. 800 horsepower on pump gas naturally aspirated. This beast can drive to the track and tear it up when it gets there without breaking a sweat as you'll see in the video below.
The foundation is an RHS aluminum block. An aluminum block compared to its iron counterpart transfers heat better and weighs 100 lbs. less. While weight reduction is helpful to drag racers, it's huge in road race and autocross for its effect on vehicle turning and braking. This block also brings a six-bolt head bolt design and the strength to easily handle this power level. Every RHS block is CAT scanned to assure that you'll receive a perfect casting. We finish machine them to perfection on our 4-axis CNC mill and CNC diamond hone.
Do you prefer Dart blocks? Happy with a great iron block? This package is also available with Dart LS Next aluminum and iron blocks. The Dart iron block is their SHP LS Next which we upgrade from main bolts to main studs.
The rotating assembly starts with a Callies Compstar center counterweighted crank. The extra counterweights increase stiffness by 25% and reduce harmonics. This in turn enhances longevity and virtually eliminates uneven bearing wear. The forged Callies Ultra H-beam rods and Diamond Race Series pistons complete a short block that you won't need to worry about.
Engines need to breathe for power and our CNC ported All Pro heads do an exceptional job. Like the short block, All Pro heads are stout. Made in the USA from 100% virgin alloy, they have a deck thickness up to 1 inch. We use these same heads for mega-power twin turbo builds. The unique port work, combustion chambers and valve job are all CNC machined on our 5-axis and Newen seat & guide machine. The COMP hydraulic roller cam and BSR shaft rockers provide performance and valve train stability across the RPM range.
The engine shown in this ad has an MSD Atomic intake manifold and it works great across the full RPM band. That being said, we can offer a range of intake manifolds to suit your exact needs, whether for optimal performance in a specific RPM range or aesthetics.
Wondering about the ECU? This package includes a Holley Terminator X engine management system with the tune from your dyno session. These units are self learning allowing them to adapt to your vehicle and driving patterns after installation without need for a chassis dyno. Once again, we can offer options that bring in additional functionalities. For example, a Terminator X-Max allows drive-by-wire and can act as the transmission controller. We have other options for such features as torque management, launch control and more.
This powerplant can be dropped into about anything. Its standard configuration is without a serpentine system and with a GM oil pan appropriate for an LS-equipped vehicle. Once again, choices abound including anything from re-use of your OE serpentine if you were already running an LS to a fully custom accessory system. The standard oil pan can be replaced with an optional retrofit oil pan such as the Moroso pan on this build or a Dailey dry sump system for the serious competitors. We will be happy to walk you through the options to get the one best for you. This is a custom engine that we will gladly tailor to exactly what you want. Need a transmission too? Happy to hook you up with one paired exactly to your engine.
Give us a call at 815-725-2727 to get the process rolling toward your dream engine build.
