This engine specification is designed for typical track day use and those running up to 550 hp power levels with the proper supporting modifications. CYLINDER SUPPORT SYSTEM INFORMATION The Cylinder Support System is a proven method of strengthening open deck engine blocks while maintaining OEM integrity.
