These are actual used aluminum pistons and rods from one of legendary Engine builder Steve Schmidt's 500 c.i.d. Pro Stock Engines. Steve has personally autographed and dated each one. Would you like to have a piece of a 1300+ horsepower 200+ MPH Pro Stock Engine, one of these would make a perfect addition to your desk or trophy shelf. This combination costs $200.00 when installed new in a Pro Stock Engine.
