Description

Our "Power Adder Series" is designed specifically to be able to add a Supercharger or Turbo(s), taking performance and horsepower to the extreme. This combination utilizes the industry leading Dart LS Next SHP block, all forged internals, and 9:1 compression to ensure your boosted application can thrive. Our LS3 cylinder heads and in-house designed camshaft makes this boost ready long block at home on the track or in a wicked street machine. This one comes drop-in-ready with a BDS 10-71 blower, dual Quick Fuel carbs and 58x Holley smart coils.

Talk about performance potential! GM’s LS platform – essentially the new-age small block Chevy – distilled decades of racing technology into factory form.

Our turn-key LS crate engine packages range from 370 to 441 cubic inches and are based on the legendary LS platform. The unique combinations you’ll find at Prestige Motorsports are designed to add low-end power and muscle-car sound to this line that provides an excellent platform for turbochargers. Our LS crate engines offer substantially more horsepower and will bring your hot rod into the 21st century. Every custom engine is dyno tested before it ships.

POWER ADDER SERIES

Looking for the ugly, nasty motors that separate the boys from the men? The Power Adder Series will let you add a supercharger, turbocharger, or nitrous. You’ll start with an aftermarket block and a substantially upgraded rotating assembly, heavy-duty forged pistons, and an array of camshaft and cylinder head options. Other parts vary by build and application. From the choice of components to their combination and tooling, our Power Adder Series is the cream of the crop, built to withstand harsh conditions and a ridiculous amount of power.

NOTE: Some engine listings may show similar items or optional products and are not included in final price.

DYNO


DYNO TESTING
Dyno testing not included in long block price. Here at Prestige Motorsports, our “Dyno Promise” means that we dyno test every engine we build to verify the quality of our work, the integrity of each component, and the reliability of every engine we construct. Then, we deliver the dyno results for your project directly to you, the customer. Hours for dyno testing will be calculated with the purchase of the fuel and ignition group per engine order.

Engines will produce +/- 2% of advertised power at the flywheel. Advertised power levels are achieved using an electric water pump and specific induction and exhaust systems. Power will vary after pulley systems are installed or if changes are made to the induction or exhaust system (e.g. camshaft, cylinder head, compression, intake manifold, exhaust headers, air filters, etc.). Chassis dyno results measure power at the wheels and only calculate flywheel horsepower. Wheel horsepower is affected by a variety of vehicle-specific criteria including driveline design, body and chassis flex, air intake location, etc. Therefore, calculating flywheel horsepower from wheel horsepower is not an accurate representation of actual flywheel horsepower.

WARRANTY

Prestige Motorsports offers a limited warranty on engines for a period of 1 or 3 years with unlimited mileage. Our warranty covers the base engine from the intake manifold to the oil pan. Add-on accessories such as ignition components, fuel delivery systems, pulley kits, and belt-driven components are covered by their manufacturer’s warranty only.

ENGINE WARRANTY OUTLINE
Upon receiving your engine, you are required to register your engine for a warranty. The form is included in the paperwork you receive with the engine. Fill out the form and return in the mail to our physical address, or you may email it to sales@prestigemoto.com. You can also download the form HERE.

If you experience any issues or concerns with your engine, you MUST contact us before any work or diagnostics are performed. We will discuss the concern and give you specific direction on the next steps. If we feel the engine needs teardown for further assessment or repair, the customer is responsible for any time and labor costs of preparing the engine for shipping including removal from vehicle and packaging fees. Prestige Motorsports will arrange pick-up of the engine and cover the cost for delivery back to Prestige Motorsports.

Prestige Motorsports will perform a thorough assessment of the engine and determine the root cause of the concern. If the root cause is determined to be a component failure or assembly error, Prestige Motorsports will repair or replace the engine, retest, and deliver back to the customer at no charge.

If the root cause is determined to be the result of improper use or inflicted by an outside source, customer or otherwise (common examples, not an exhaustive list, of root causes that are not covered under warranty, include overheating, incorrect ignition timing, incorrect air/fuel ratios, use of power-adders, over-revving, and incorrect oil level), the customer will be invoiced for delivery charges incurred by Prestige Motorsports for retrieving the engine, as well as a tear-down and assessment labor time.

Prestige Motorsports will also provide an estimate for parts and labor to repair or replace the engine, including the cost of delivery back to the customer. The customer then has the option to approve the recommended repairs or retrieve the engine in its current state from Prestige Motorsports.

Ultimately the engine will tell the story. Prestige Motorsports keeps detailed records of root cause analysis which may include photos or videos if the customer has questions about the results. However, it is at the sole professional discretion of Prestige Motorsports as to the root cause of failure.
