The Briggs & Stratton Vanguard Big Block V-Twin is a series of American piston engines, designed and produced by Briggs & Stratton of Wauwatosa, Wisconsin for use in commercial applications. They have also been adapted for use as ultralight aircraft engines.[1] Design and developmentThe engine is a V-twin four-stroke, {{convert|895|cc|cuin|1|abbr=on}} or {{convert|993|cc|cuin|1|abbr=on}} displacement, fan-driven air-cooled, gasoline engine design. The larger displacement is achieved by increasing the stroke from {{convert|78|to|87|mm|in|1|abbr=on}}, but using the same bore of {{convert|86|mm|in|1|abbr=on}}. In aviation applications it is used as a direct drive engine, turning a propeller without a reduction drive. It employs a single electronic ignition system and produces {{convert|25|to|37|hp|kW|0|abbr=on}} at 3600 rpm.[1] Variants
Model with {{convert|895|cc|cuin|1|abbr=on}} displacement, bore of {{convert|86|mm|in|1|abbr=on}}, a stroke of {{convert|78|mm|in|1|abbr=on}} and a power output of {{convert|25|to|33|hp|kW|0|abbr=on}} at 3600 rpm[1][2]
