Eagle Chevy 327 SJ 3.250in Crank 2.300in Mains 6.125in H-Beam 4.040in Pistons Rotating Assembly

This Eagle Chevy 327 SJ rotating assembly gives you the core components to rebuild or upgrade your small-block Chevy engine. You get a forged 4340 crankshaft with a 3.250-inch stroke and 2.300-inch main journals, a set of 6.125-inch H-beam connecting rods featuring 7/16-inch ARP 8740 bolts, and a set of Mahle 4.040-inch forged 4032 flat-top pistons with a -5cc dish. This assembly also includes plasma-moly file-fit piston rings and King XP rod and main bearings to get your engine rotating smoothly.

This is a competition-level assembly built for demanding use, including racing applications with nitrous or forced induction. The forged 4340 steel crankshaft is strong enough to handle significant stress, and the H-beam connecting rods with ARP bolts offer a solid connection between the crank and pistons. The Mahle pistons are forged from 4032 aluminum, which is known for its good thermal expansion properties, making them suitable for higher temperatures. The plasma-moly file-fit rings allow for precise gapping to match your specific engine build and cylinder wall finish, and the King XP bearings are designed for high-performance lubrication needs.

When building a high-performance engine, it's crucial to ensure all components are balanced and clear properly. This assembly is designed for the Chevy 327 small journal engine. Please note that this part is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic for specific installation and balancing recommendations to ensure optimal performance and longevity.
