Even though it is the little brother of the 427" Cobra, the Smeding Performance 347" Cobra, when provoked, strikes with a vengeance. With a broad, kick-in-the-pants torque band and brutish horsepower, this pump-gas-friendly powerhouse gets with the program. Using all premium parts in a proven combination, along with precise machining, careful hand-assembly, and then broken-in, tuned and tested on our in-house dyno, you are guaranteed the power we say it makes.
