Eagle Chevy 350 1Pc 3.750in Crank 6.000in H-Beam -5cc Flat Top 4.060in Pistons Balanced Assembly

If you're building a high-performance Chevy 350 for serious racing, especially with power adders like nitrous or turbochargers, a balanced rotating assembly is a critical starting point. This Eagle Competition Rotating Assembly is designed to handle the stresses of demanding engine builds. It includes all the core components you need to get your short block assembled and ready for the machine shop.

This assembly features a forged 4340 steel crankshaft with a 3.750-inch stroke, providing a good displacement increase for a 350 block. Paired with it are 6.000-inch H-beam connecting rods, known for their strength and reliability under high loads. These rods are secured with 7/16-inch ARP 8740 bolts, a popular choice for their durability. The pistons are forged 4032 aluminum from Mahle, featuring a -5cc flat top design and a 4.060-inch bore size, which is standard for a .060 over 350. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your specific application and ensure good sealing. For the bearings, Eagle has included King XP rod and main bearings, offering robust protection for the crankshaft and connecting rods.

This assembly comes balanced from Eagle, saving you a significant step and cost at the machine shop. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder and manufacturer's instructions for proper installation and break-in procedures.
