Speedmaster PCE274.1088 I-Beam Race connecting rods are purpose-built for high-performance Chevy Big Block 454 engines. Forged from premium 4340 chromoly steel, these rods measure 6.700" center-to-center length with a 2.200" big end journal diameter and a .990" pin bore, delivering the strength and dimensional precision demanded by serious race and street/strip builds.
The I-beam profile provides an excellent strength-to-weight ratio, while the pressed-in bronze small-end bushings support a full-floating wrist pin setup for increased durability under high-RPM and high-load conditions. Sold as a set designed to fit Chevrolet Big Block 454 applications, these rods are an ideal upgrade for builders chasing reliable power on the track or the strip.
