Description

When you need nothing short of extreme power for your boat, 632 Big Block Chevy Marine engine is a great option. With hundreds of hours in development under our belt, Prestige Motorsports has turned the prop on the Marine market in a powerful way. This engine has to be experienced in order to appreciate!

Our 454 Big Block Chevy crate engines run from 489 to 632+ cubic inches and are based on the legendary 454 Big Block Chevy!

These oversized crate engines provide an excellent platform for power adders, delivering impressive performance specs and deep, ground-pounding sound. Thanks to the custom machining, hand-picked components, and dyno testing unique to Prestige Motorsports, you can expect durability, strength, and excellent drivability – not to mention great value. Whether you drop one of these turn-key engines into your Offshore boat or Lake Cruiser, it’ll be sounding like the performance engines of the ‘60s and ‘70s!

MARINE SERIES

Our Marine development team incorporates dyno charts, testimony from boat builders, and real-world conditions from Florida, Louisiana, and Texas to design engines around your boat performance needs. We look at the extended periods of time that a Marine engine is under heavy load and design the engine for specific RPM ranges, concentrating primarily on low-end torque and mid-range power. The resulting Marine engine packages deliver performance that’s hands-down better than anything you’ve used before. For builders, we also offer a dealer discount.

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.

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 directions 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 it 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.
