Speedmaster's I-Beam Pro connecting rods (PN 1-274-033) are forged from premium 4340 steel and sized at 6.125" center-to-center length with a 2.100" big-end bore and .927" pin bore, delivering the strength and dimensional precision demanded by high-performance and racing Chevy Small Block 350 applications. The robust I-beam profile provides an excellent balance of rigidity and weight, making these rods a reliable foundation for builds pushing beyond stock power levels.
Each rod ships with ARP 2000 fasteners pre-installed, ensuring superior clamping force and stretch consistency compared to factory-style hardware. Designed as a direct-application set for the Chevy SBC 350, these Speedmaster connecting rods are an ideal upgrade for street/strip and track builds where reliability and precise fitment are non-negotiable.
