NRE Alien Fuel Injected 632 – Daily Driver Series | 740 HP EFI Big Block

The NRE Alien Fuel Injected 632 Daily Driver Series is engineered for enthusiasts who want uncompromising big-block performance with true street manners. Delivering 740 horsepower at 6,000 RPM, this engine combines brutal torque, lightning-fast throttle response, and the unmistakable “nasty” hot rod sound with modern electronic fuel injection and daily-driver reliability. It’s built to be driven, not just admired.

At the heart of this package is the signature NRE Alien intake, featuring a stealthy design with hidden injectors and sensors while maintaining an ultra-low 9-inch total intake height. This allows the engine to fit under most factory and custom hoods without requiring a tall cowl, making it ideal for classic muscle cars, hot rods, restomods, and pro-touring builds. A fully sequential, self-learning ECU automatically compensates for elevation and environmental changes, delivering smooth drivability anywhere in the world.

Performance & Driving Character

This 632 cubic inch big block delivers massive, usable torque throughout the RPM range, making it exceptionally responsive in real-world driving. The custom NRE hydraulic roller camshaft provides an aggressive, authoritative idle while remaining maintenance-free—no valve adjustments required. The result is an engine that feels raw and old-school, yet behaves with the refinement of modern EFI technology.
