Speedmaster part number 1-274-024 delivers a set of H-beam connecting rods precision-forged from 4340 chromoly steel, engineered for Big Block Chevy 454 applications. Measuring 6.385" center-to-center with a 2.200" big-end journal and a 0.990" small-end pin bore, these rods are built to handle the demands of high-performance and racing engine builds where strength and reliability are critical.
Each rod ships complete with ARP 8740 rod bolts, a proven fastener choice trusted by engine builders for their superior clamping strength and fatigue resistance. The H-beam profile provides an excellent balance of rigidity and weight, making this set a smart upgrade over factory connecting rods for BBC 454 performance builds.
