JE Pistons 350SBC INVDOME 23DEG Set of 8 Pistons

Forged from 2618 aluminum, these JE Pistons are built for high-demand performance applications. This set is specifically designed for the 350 Small Block Chevrolet engine with a 23-degree cylinder head configuration, featuring an inverted dome to help achieve your desired compression ratio. The 4.030-inch bore size is a common upgrade for many 350 builds, offering a slight increase over the stock bore for improved displacement and airflow.

JE Pistons brings over 75 years of experience to the table, engineering and machining these pistons entirely in the USA. They utilize a proprietary Forged Side Relief (FSR) design, which reduces skirt width to minimize friction and power loss while also saving weight. Depending on the specific application, these pistons may also feature an accumulator groove to reduce combustion gas pressure, preventing ring flutter and improving ring seal for consistent power delivery. A skirt coating, if included for your specific application, further reduces friction and wear on the piston skirts and cylinder walls, contributing to quieter operation and longer life.

This set includes eight pistons, each with a 1.250-inch compression distance and a 0.927-inch pin diameter, ready to be installed in your performance 350 SBC build. Please note that these pistons are not CARB approved and cannot be shipped to California.
