Magic number engine is for a ZR1!
GM has announced today that it has hit a milestone with its iconic small-black engine. GM has built its 100 millionth small block engine with the magic number coming 56 years after the first small block was produced. The special engine was an LS9 that was built at the Performance Build Center and will find its way under the hood of a awesome Corvette ZR1.
The LS9 that is the 100 millionth engine will ultimately be a supercharged engine with 638hp and is being hand built. The LS9 is the most powerful engine ever built by GM for a regular production car. The small block Chevy engine can be found in all manner of hot rods and muscle cars running the street as well as a number of factory GM vehicles from trucks to old school muscle cars.
The 100 millionth engine will be kept by GM as part of its historical collection. The normal small block Chevy engine used in the Corvette is a LS3 with 430hp and get 26mpg on the highway. The engine pushes the Corvette to 60 mph in right at four seconds and through the quarter mile in a bit more than 12-seconds.
