About this part

Product Details

This is the Eagle Street & Strip Balanced Rotating Assembly, built for Chevy 400 engines. It’s designed for street vehicles running on pump gas and naturally aspirated setups. This assembly includes a 3.750-inch cast crankshaft, 6.000-inch I-beam connecting rods with 3/8-inch ARP 8740 bolts, and forged 4.155-inch pistons with an inverted dome. It also comes with plasma-moly file-fit piston rings and King rod and main bearings.

The forged 4032 aluminum pistons feature a -16cc inverted dome, which is a key detail for managing compression ratios in performance street applications. The plasma-moly file-fit rings give you flexibility during installation to achieve a proper seal against the cylinder walls, which is crucial for good compression and oil control. Eagle includes King rod and main bearings, known for their solid performance in street and strip applications. This assembly is balanced from the factory, saving you a significant step and ensuring proper rotating assembly balance right out of the box.

Keep in mind that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. It's important to check local regulations regarding emissions compliance for your specific build. This balanced rotating assembly is a well-built foundation for a performance street engine.
