Overview:

BluePrint Engines unleashes pure intimidation with the 632 c.i. Pro Series Blackout Reaper Edition—an 815-horsepower monster wrapped in stealth, attitude, and unapologetic big-block brutality. This Reaper is built with Pro Series forged internals, precision machining, and bottom-end strength engineered for high-torque, high-RPM abuse, and street-or-strip domination. On the outside, it’s all sinister style: fully deluxe dressed - premium accessories, blackout finishes, and a blacked-out pulley kit that makes any engine bay look deadly serious. If you want maximum cubic inches, old-school carbureted fury, and a look that says don’t even think about it, the Blackout Reaper 632 is your throne of power.
