MOPAR 68643793AA Hurricrate Cat3 Twin Turbo Crate Engine

The HurriCrate series of crate engines employs state-of-the-art engineering and technologies that include two low-inertia, high-flow turbochargers for rapid response to throttle inputs, Plasma Transfer Wire Arc (spray bore) coating in the cylinder bores for an ultra-thin, low-friction wear surface, and high-pressure direct fuel injection. The HurriCrate Cat3 delivers up to 550 horsepower and delivers its max 531 lb.-ft. of torque at just 3,500 rpm.Cat3 Crate Engine Highlights
