Speedmaster PCE274.1089 I-Beam Race Connecting Rods are precision-engineered from high-strength 4340 steel and feature a classic I-beam profile designed for demanding performance and racing applications. Each rod is built to exacting dimensions — 6.800" center-to-center length, 2.200" big-end bore, and .990" pin bore — with bronze bushings installed at the small end to support floating wrist-pin configurations.
Designed to fit Chevy Big Block 454 engines, these rods deliver the strength and reliability needed for high-horsepower builds where stock connecting rods simply won't hold up. Whether you're building a street/strip combination or a dedicated race engine, the Speedmaster PCE274.1089 rods offer a performance-focused solution for your BBC rotating assembly.
