Roush Industries – other road engines: the collective page of LPG and CNG conversion engines based on the Ford 6.8- and 7.3-litre V8/V10, 269 to 350 hp, for school buses, motorhomes and vans
Roush Industries (Roush CleanTech), headquartered in Livonia, Michigan, converts Ford petrol engines to run on propane autogas and compressed natural gas. The engine-family codes in the register point with 07.3 to the 7.3-litre V8 and with 06.8 to the older 6.8-litre V10 from Ford's line-up; the models in the vehicle column, from the Blue Bird Vision Bus through the E-Series and F650/750 to the Motor Home, match the typical Ford chassis for school buses, shuttle buses, motorhomes and medium-duty trucks.

The register lists here 23 versions with 269 to 350 hp at a rated speed of 3,750 to 4,250 rpm, all with sequential fuel injection. LPG dominates the fuel field with 22 versions against one CNG version. Maximum torque ranges from 386 to 468 Nm at 3,072 to 3,900 rpm, model years from 2016 to 2026.
With these conversion engines, Roush serves the North American market for alternative fuels in fleet and commercial vehicles, especially school-bus fleets and municipal vehicles, for which LPG and CNG drive offer tax and environmental advantages over diesel.
When buying used, on these conversion engines the condition of the gas system and its seals, the service history of the gas-specific spark plugs and valve seats, and the operating hours of the fleet the vehicle came from matter especially; the underlying Ford base engine itself follows the well-known service intervals for petrol V8/V10s. Spares for the gas system run through the Roush CleanTech network, for the base engine through Ford.
