Superb 2000 Ford Cosworth Indy Car engine blank features 10 signatures including Michael Andretti. Measuring 60" long and 12" across at the top tapering to 30" at the bottom, the gray cover - also known as an engine diaper - surrounds the engine compartment to prevent fluids or parts from getting on the track in the event of engine failure. The son of legendary Mario Andretti, Michael has carved out an exceptional career in his own right, having won four IndyCar Championships to date.
