Aeroflow Performance cast iron engine blocks are a strong foundation for street performance builds that demand durability, precision, and value. This Ford Cleveland block is designed with a 4.125 inch bore, 9.200 inch deck height, and 2.750 inch mains, giving you a robust starting point for a serious engine package. Made from premium high strength Class 32B iron, it is a semi finished bare block that reduces the amount of machine work needed to suit your build requirements.
