At the heart of this assembly is a forged 4340 steel crankshaft with a 3.750-inch stroke, providing the foundation for increased displacement and torque. Paired with this are Eagle's 5.700-inch long 4340 H-beam connecting rods, known for their strength and durability under high RPM and load. These rods are secured with 7/16-inch ARP 8740 bolts, a name trusted for their reliability in extreme conditions. The pistons are forged 4032 aluminum from Mahle, featuring an inverted dome design with a -26cc volume to achieve a specific compression ratio with your cylinder heads, and they come with plasma-moly file-fit rings. To complete the package, King XP rod and main bearings are included, offering excellent wear resistance and performance.
This assembly is designed for competition use and is not CARB approved, meaning it cannot be shipped to California. It's a comprehensive kit for anyone serious about building a high-output Chevy 350 engine.
