The selection of fasteners for securing the connecting rods to the crankshaft in a Big Block Ford 460 engine is a critical factor in engine performance and reliability. These fasteners, typically manufactured from high-strength steel alloys, must withstand significant tensile and shear forces generated during the engine’s combustion cycle. Examples include ARP 2000 or Custom Age 625+ connecting rod bolts, often chosen based on the engine’s intended use and power output.
Properly chosen and installed connecting rod bolts are essential for preventing connecting rod failure, which can lead to catastrophic engine damage. The quality of these bolts directly impacts the engine’s ability to handle increased cylinder pressures and higher RPM. Historically, upgrading these bolts has been a common practice in performance engine builds to increase overall engine durability and longevity.
