The Smeding Performance 572" Blown, for the guy that wants to be King Kong of the street, it is the biggest and baddest engine we produce. If you love the look of a polished 8-71 blower and dual-quads sticking through the hood, and that unmistakable horsepower-inducing whine of a blower, this is the engine for you. Using top quality parts, the latest in engine machining techniques, along with precision engine assembly, ensures you of being the baddest boy on the block. Checking in at 900 horsepower and 880 lbs/ft of torque, the 572" Blown makes more torque at 2500 RPM than any two normally-aspirated small-blocks. That is ground shaking power, and yet it runs on 91-octane pump gas. When this engine comes rumbling down the street, the timid and faint of heart run and hide.
