CARB Approves Roush Propane-Powered F-250 and F-350 Pickups

Let’s just say I’m not exactly a fan of the California Air Resource Board, or CARB. For all their good intentions, they cause a lot of headaches with unintended consequences of sometimes poorly conceived ideas–especially for those of us who enjoy performance cars.

But every now and then they get something right. And while Roush is a name most often associated with supercharged Mustangs, the company is also well known for its propane conversions. CARB recently approved both the F-250 and F-350 Roush propane conversions for street use. Yay!

CARB approved the F-150 propane conversion last year, but it had a smaller 4.6 liter engine. The F-250 and F-350 are heavier duty trucks with bigger 5.4 liter engines. CARB has stricter emissions requirements than the Federal mandates, and numerous states (including my own Connecticut) have adopted the stricter guidelines. It can get confusing.

But with the F-250 and F-350 from Roush approved by CARB, they are basically all set to go. While I don’t care for CARB, I do like propane conversions. The domestically produced fuel offers a 20% reduction in nitrogen oxide, a 60% reduction in carbon monoxide, and fewer particulate emissions. Some power loss can occur, but it is a conversion that can be performed on many cars right now, rather than years from now. Plus, Roush even has a pair of propane-powered Mustangs out on a campaign tour. They also have plans to tackle the E-series of vans soon, including the E-450 with the 6.8 liter V10 engine.
