Wiseco Chevy BB DRAG 1.270inchCH (6240A100) Piston Shelf Stock Kit

If you're building a serious drag racing engine for your Chevrolet Big Block, you need pistons that can handle the extreme demands of competition. This Wiseco Professional Series piston set is built for those heavy to severe duty race applications where every ounce of performance and durability counts. They are designed to remove your limits and let you push your engine to its absolute maximum potential.

These pistons are forged and machined in the USA from 2618 aluminum, a material chosen for its improved tensile strength under high stress. Wiseco has incorporated precision ring grooves, anti-detonation grooves, and other features to enhance ring seal, ensuring efficient combustion and preventing blow-by. The fully machined crown is ready for your build, and the forced pin oiling system helps keep the wrist pins properly lubricated. Additionally, the ArmorGlide skirt coating reduces friction, resists seizure, and contributes to quieter operation, all critical factors in a high-performance racing engine.

This set includes eight pistons, each designed for a 4.600-inch bore with a 1.270-inch compression height and a 0.99-inch pin diameter. Please note that these pistons are not CARB approved and cannot be shipped to California. For the ultimate in racing engine performance and reliability, this Wiseco Professional Series piston set is a solid choice.
