Eagle Chevy 327 SJ 3.250in Crank 2.300in Mains 6.125in H-Beam 4.060in Pistons Rotating Assembly

Starting with a forged 4340 steel crankshaft featuring a 3.250-inch stroke, this Eagle rotating assembly is built for serious performance. The crankshaft is designed with 2.300-inch main journals, a common specification for many Chevy small block applications, and pairs with 6.125-inch H-beam connecting rods. These rods are equipped with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high stress.

The assembly includes forged 4032 aluminum pistons from Mahle, sized at 4.060 inches with an 11.1cc dome volume, designed to work with plasma-moly file-fit piston rings. This piston and ring combination is crucial for achieving optimal compression and sealing, especially in demanding applications like racing, nitrous, or forced induction setups. To complete the package, King XP rod and main bearings are included, offering robust performance and durability for the critical rotating components.

This rotating assembly is a comprehensive solution for rebuilding or upgrading your Chevy 327 small journal engine. It’s important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult manufacturer instructions for proper installation and break-in procedures to ensure longevity and performance.
