Speedmaster part number 1-274-037 delivers a complete set of H-beam connecting rods engineered specifically for the Chevy Small Block 350. Forged from aerospace-grade 4340 chromoly steel and featuring a 6.000" rod length, 2.100" big-end bore, and .927" pin bore, these rods are built to handle the stress of high-performance and racing applications while maintaining precise dimensional consistency for balanced rotating assemblies.
Each rod ships ready to install, pre-fitted with industry-trusted ARP 2000 fasteners that provide exceptional clamping force and fatigue resistance under sustained high-RPM loads. The H-beam profile optimizes strength-to-weight ratio, making this set an ideal upgrade for street/strip and forced-induction SBC 350 builds demanding reliable, long-term durability.
