Eagle Chevrolet Small Block Rotating Assembly w/ 4.155in Bore 3.750in Stroke -5cc Dome

Starting with a 4.155-inch bore and a 3.750-inch stroke, this Eagle rotating assembly is built for Chevrolet small block engines looking for a solid foundation for street performance. The MAHLE 4032 forged pistons feature a -5cc dome, which is a common choice for naturally aspirated builds aiming for good compression on pump gas. These pistons are paired with 5.700-inch I-beam connecting rods, secured with 3/8-inch ARP 8740 bolts, offering a strong and reliable link between the pistons and the crankshaft.

The cast crankshaft is designed for a 3.750-inch stroke, working in harmony with the pistons and rods to create a well-balanced rotating assembly. Eagle includes KING SI rod and main bearings, which are known for their durability in street applications. The plasma-moly standard gap rings are also a practical choice for street use, helping to ensure good sealing and oil control. This assembly is intended for pump gas, naturally aspirated street vehicles, making it a popular option for engine rebuilds or upgrades where reliability and performance on regular fuel are key.

When assembling your engine, pay close attention to the manufacturer's instructions for proper balancing and installation of the bearings. This rotating assembly is a significant step in building a robust engine, and ensuring each component is installed correctly will contribute to its longevity and performance on the street.
