Eagle Chevy 400 3.750in Crank 5.700in I-Beam Rods -7cc Flat Top 4.185in Pistons Rotating Assembly

This Eagle Street & Strip rotating assembly is a well-built package designed for Chevy 400 engines intended for pump gas, naturally aspirated street applications. You get a 3.750" cast crankshaft, 5.700" I-beam connecting rods fitted with 3/8" ARP 8740 bolts, hypereutectic Speed Pro flat top pistons with a -7cc dish and a 4.185" bore, plasma-moly standard gap rings, and King rod and main bearings. This combination is put together to offer a solid foundation for your engine build.

The cast crankshaft is a strong choice for street use, while the I-beam connecting rods are a popular option for their balance of strength and weight. The inclusion of ARP 8740 bolts means you're getting reliable hardware for the connecting rods, which is crucial for engine longevity. The hypereutectic pistons are designed to work well with pump gas and feature a flat top with a -7cc dish, which will affect your final compression ratio depending on your cylinder head volume. The plasma-moly rings are standard gap, suitable for many builds, and the King bearings are a well-known name in engine components, providing good performance for the rod and main journals.

This assembly is intended for builders looking for a complete rotating assembly to get their Chevy 400 engine project underway. It’s important to note that this assembly is not CARB approved and cannot be shipped to California.
