CP Piston Bullet Race Series Small Block Chevy 4.000 Bore 3.480 Stroke 5.700 Rod Set Of 8

This set includes eight forged pistons, designed for Small Block Chevy engines with a 4.000-inch bore, 3.480-inch stroke, and intended for use with 5.700-inch connecting rods. These are CP Pistons' Bullet Race Series, built for high-performance applications where durability and consistent performance under stress are critical. The forged construction means these pistons start as a solid block of aluminum that's heated and hammered into shape, creating a stronger, more resilient grain structure than cast pistons. This makes them much better at handling the extreme pressures and temperatures found in race engines or heavily modified street performance builds.

The Bullet Race Series is known for its advanced skirt designs and optimized ring land configurations, which help reduce friction and improve sealing for better power output and oil control. CP Pistons uses specific forging dies and machining processes to ensure precise dimensions and a well-balanced rotating assembly, which is crucial for engine longevity at high RPMs. These pistons are intended for builders who are assembling a performance engine from the ground up and need components that can withstand significant abuse. They are a solid option for those looking to push the limits of their Small Block Chevy.

When installing these pistons, remember they are a critical component of your engine's rotating assembly. Proper balancing of the entire assembly—crankshaft, connecting rods, pistons, and flywheel—is essential for smooth operation and to prevent premature wear. Always refer to the manufacturer's installation instructions for specific details regarding ring gap, piston-to-wall clearance, and assembly procedures.
