MORE DISPLACEMENT. MORE POTENTIAL. THE SAME LEGENDARY SMALL BLOCK FORD PLATFORM.
THE 363 VIPER TAKES OUR PROVEN 347 STROKER COMBINATION ONE STEP FURTHER.

Featuring a premium aftermarket engine block, fully forged rotating assembly, high-flow aluminum cylinder heads, and a carefully developed hydraulic roller valvetrain, this combination delivers impressive torque, crisp throttle response, and exceptional performance potential.
The additional cubic inches provide an opportunity for even greater power delivery without sacrificing the compact dimensions and versatility that make the 302-based platform so desirable.
From a refined, powerful street cruiser to an aggressive, hard-hitting performance combination, each 363 Viper can be tailored to your specific vehicle, driving preferences, and performance goals.

Why Choose a Reid’s speed Shop Crate engine:
When purchasing a crate engine, you have many options available—from large production companies to smaller independent builders. At Reid’s Speed Shop, the difference is simple: this isn’t mass production—it’s personal craftsmanship.
Every engine is carefully assembled with attention to detail and built using combinations that have been thoughtfully researched and proven to work together. Rather than being one of hundreds of engines moving down an assembly line, your engine receives the kind of focus and care that only a small, dedicated shop can provide.
Communication is also a major part of the experience. Throughout the process, customers are kept informed and updated as their engine comes together. Photos and updates are often shared so you can actually see the progress of your engine being built rather than simply receiving a shipment notice when it’s finished.
Whenever possible, customers are also given the opportunity to hear their engine run before delivery. Whether in person or through a video demonstration, this allows you to see and hear the engine come to life—giving you confidence in how it runs, idles, and performs before it ever leaves the shop.
At Reid’s Speed Shop, the goal isn’t to move engines as quickly as possible—it’s to build them correctly and ensure every customer feels confident in the investment they’ve made. Building engines is more than just a job here; it’s a genuine passion and a craft that is taken seriously.
When you choose Reid’s Speed Shop, you’re not just purchasing an engine—you’re working directly with the person building it, ensuring transparency, accountability, and a level of care that large-scale production simply cannot offer.
