Ford Racing 460 Siamese Bore Engine Block

This Ford Racing 460 Siamese Bore engine block is manufactured using all-new tooling, a significant update from the well-known M-6010-A460 block. It's cast from high-strength iron and features a Siamese cylinder bore design, meaning the cylinders are cast close together. This construction allows for a wide bore range, from 4.360 up to 4.6 inches, and enables builds up to 598 cubic inches, making it a solid foundation for professional competition engines.

The block is designed with a priority main oiling system, ensuring consistent oil flow to the main bearings, which is crucial for high-performance applications. It comes equipped with nodular iron main caps, featuring 4-bolt configurations on journals 2, 3, and 4 for added strength and stability under demanding loads. The deck height is 10.322 inches, and it uses a 3-inch main journal diameter. This block is intended for a wet sump oiling system and weighs approximately 275 pounds, reflecting its robust construction.

This is a serious piece of hardware for builders looking to create a powerful 460-based engine. Keep in mind that this block is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and setup of your new engine block.
