The Buick Roadmaster was the typical American sedan of the early ‘90s with a lazy engine and comfy ride. But the Buick engineers found a way to install a Corvette LT1 5.7-liter V8 engine into the Roadmaster engine bay. The LT1 produced 300 HP in the Corvette.
But in the Buick, it pumped out 260 HP. And that was more enough horses to turn this heavy car into a proper hot rod. Despite the curb weight of over 4,400 pounds, this car could outrun most of the muscle cars of the day.
