Product Details
This Eagle Chevy 350 rotating assembly gives you a complete package for rebuilding or upgrading your engine. You get a 3.75-inch forged 4340 crankshaft, 5.7-inch 4340 H-beam connecting rods with 7/16-inch ARP 8740 bolts, and 4.030-inch Mahle 4032 forged pistons with an inverted dome design that creates a -26cc volume. It also includes plasma-moly file-fit rings and King XP rod and main bearings to get your short block assembled.
This assembly is built for demanding use, including racing applications that might involve nitrous or forced induction. The forged 4340 crank and H-beam rods are strong choices for handling increased stress. The Mahle pistons are forged from 4032 aluminum, which offers good strength and thermal expansion properties suitable for performance builds. The inclusion of ARP bolts means you're getting reliable hardware for the connecting rods, and the King XP bearings are designed for performance applications.
When putting this assembly together, remember that the plasma-moly rings are file-fit, meaning they need to be gapped to your specific cylinder bore and application before installation. This is a standard procedure for performance engines to ensure proper sealing and oil control. This assembly is not CARB approved and cannot be shipped to California.
