416 LS3 Stroker
416 ls3 Stroker Crate Engine - Super Street Series - 575 HP
NOTE: Not ready to ship immediately. Engine is built to order.

Our turn-key LS crate engine packages range from 393 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.

Super Street Series

When your street or strip car needs more power and durability, it’s time for a performance-minded upgrade. Our bigger, beefier Super Street Series motors will give you an aftermarket block with larger bore sizes for more cubic inches that’s able to handle more power. You’ll get a hydraulic or solid roller tie bar lifter and an all-forged rotating assembly. These are motors for the guy who wants to put the pedal to the metal and beat the living daylights out of his car.

Prestige Motorsports Mission Statement
Prestige Motorsports Core Values

Value

We genuinely believe in the value of Prestige Motorsports engines and vehicles. We earn your business by building and delivering top-quality products that perform at the highest level. We are willing to prove that value is not determined solely by the price paid for a product. Value includes how well a product performs, how reliable it is throughout its lifespan, and the customer service and support that backs it up.

Quality

We use and sell components that we have found, through our years of experience, to be the highest quality and most reliable for each given application. We take pride in the quality of our work and never cut corners.

Performance

We work with suppliers to design and select components that perform at the highest level for each individual goal-driven application. We are always working to improve our entire line of engines so that we can offer the best performance possible. We are committed to delivering the performance we promise. We refuse to make inflated performance claims. The numbers we advertise are accurate, and we will not ship an engine until it meets or exceeds those standards.

Service

We have an experienced and knowledgeable staff committed to offering the best service and advice possible. Our team works with customers to select exactly the right products for their performance needs and goals. They also answer questions to help customers get the most out of their engines and components.
