About this part

Product Details

This Eagle Competition Rotating Assembly gives you the core components to rebuild or upgrade your Chevy 327 engine. Inside this package, you'll find a 3.250-inch forged 4340 crankshaft, a set of 6.125-inch H-beam connecting rods secured with 7/16-inch ARP 8740 bolts, and 4.030-inch Mahle flat-top pistons with a -5cc dish. It also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get your rotating assembly ready for installation.

This assembly is built for demanding use, including racing applications that might involve nitrous oxide or forced induction. The forged 4340 steel crankshaft and H-beam connecting rods are strong choices for handling increased cylinder pressures and RPMs. The Mahle pistons are forged from 4032 aluminum, a material known for its good thermal expansion properties, and come with file-fit rings, giving you the flexibility to set your ring gap precisely for your specific build. The inclusion of ARP bolts for the connecting rods means you're getting reliable hardware known for its strength and consistent clamping force.

When building a high-performance engine, especially one intended for racing, the rotating assembly is the heart of the operation. This Eagle kit provides a well-matched set of components designed to work together. Remember that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or manufacturer's instructions for proper installation procedures and clearances.
