This particular story has been a long-time-coming, so firstly... sorry about that. This particular Chevelle is a little different that most that you'd be likely to see driving down... say, Woodward Avenue. The difference is in the engine bay. Making a thousand horsepower from a Chevy V8 engine is not at all unheard of, but making that power using propane instead of gasoline? Different story. Using propane allows for slightly lower emissions, so, as Autoblog already said, this is one clean hot rod.
