Blossman Services – other heavy-duty road engines: bi-fuel petrol/autogas engines on Ford and GM bases, 254 to 350 hp, model years 2015 to 2026
Blossman Services is the conversion arm of US propane supplier Blossman Gas from the south-eastern United States, certifying bi-fuel petrol/autogas engines based on Ford and GM V8/V10 base engines of 6.0, 6.8 and 7.3 litres. This page gathers the versions the register could not assign to a named model.

The register lists here 8 versions with 254 to 350 hp at 3,900 to 4,747 rpm, all with sequential fuel injection and the petrol/LPG fuel pair. The certifications cover model years 2015 to 2026 – a sign of the long, unchanged run of individual EPA engine families. Maximum torque lies between 341 and 468 lb-ft (462 to 635 Nm) at 3,072 to 4,480 rpm. The range is certified for the US market.
Bi-fuel petrol/autogas engines of this kind target fleet operators who want the lower fuel costs and emissions of autogas without giving up existing petrol infrastructure – for example school buses, municipal vehicles and delivery fleets in the south-eastern US, where Blossman runs a dense autogas filling-station network.
On a used vehicle, the inspection date of the autogas tank, the tightness of gas lines and valves, the condition of spark plugs and ignition coils, and the catalytic converter all matter. Since the engines are bi-fuel, it is also worth checking that the automatic switch between petrol and gas operation works cleanly. Service and parts for the gas system run through the Blossman network.
