Eagle Chevrolet Small Block Rotating Assembly 9.73:1 CR +.030 Bore 6in H-Beam Rods 3.75 Stroke

This Eagle Competition Rotating Assembly gives you a complete set of the core components needed to rebuild or upgrade the bottom end of your Chevrolet small block engine. Inside this kit, you'll find a forged 4340 steel crankshaft with a 3.750-inch stroke, a set of 6.000-inch H-beam connecting rods featuring 7/16-inch ARP 8740 bolts, and forged 4032 aluminum pistons designed for a 4.155-inch bore with a -16cc inverted dome. This assembly is balanced and ready to go, aiming for a 9.73:1 compression ratio with the specified pistons and a typical 64cc cylinder head. It also includes plasma-moly file-fit piston rings and King XP series rod and main bearings for robust lubrication and durability.

Eagle designed this rotating assembly for demanding applications, including racing use with nitrous oxide or forced induction. The 4340 forged steel crank and H-beam rods are well-built to handle the increased stresses these setups create. The Mahle pistons are forged from 4032 aluminum, which offers a good balance of strength and thermal expansion properties, making them suitable for high-performance street and strip use. The included file-fit rings allow for precise control over piston-to-wall clearance, which is crucial for optimal ring seal and performance, especially in boosted or nitrous applications. King XP bearings are known for their strength and ability to maintain oil film under high loads.

This assembly is configured for engines with 350 mains, commonly found in Chevrolet 350 and 400 small block engines. It's important to note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and balancing procedures to ensure the longevity and performance of your engine build.
