Alliance Autogas has gained approval from the U.S. Environmental Protection Agency to produce bi-fuel propane-autogas versions of vehicles powered by Ford’s 6.8L V-10 and General Motors’ 6.0L V-8 spark-ignited engines through its equipment developer Blossman Services, Inc. These engines are typically found in work trucks, shuttle buses, school buses, street sweepers, and strip chassis. Popular vehicle models with these engines include the Isuzu NPR, Ford F-450, F-550, F-650, Chevrolet Express van, Workhorse step van, and Freightliner Custom Chassis vehicles.
