Eagle Pontiac 455 4.250in Crank 6.800in I-Beam Rods -22cc 4.155in Pistons Rotating Assembly

This is a complete rotating assembly from Eagle, specifically built for Pontiac 455 engines. It includes a forged 4.250-inch crankshaft, 6.800-inch I-beam connecting rods with ARP 7/16-inch bolts, and Mahle 4.155-inch inverted dome pistons with a -22cc volume. This assembly is designed to handle the demands of serious racing applications, including those using nitrous or forced induction.

The forged 4340 steel crankshaft is a strong foundation for high-horsepower builds. The I-beam connecting rods are also forged from 4340 steel, a well-known material for its strength and durability under stress. They come equipped with 7/16-inch ARP 8740 bolts, which are a popular choice for their reliability in performance engines. The Mahle pistons are made from 4032 aluminum, known for its good thermal expansion properties, and feature an inverted dome design with a -22cc volume, which will affect your compression ratio depending on your cylinder head chamber size. They also come with plasma-moly file-fit rings, allowing for precise ring gap setting during assembly. King XP rod and main bearings are included, offering robust lubrication and wear protection for high-load conditions.

This assembly is a comprehensive package for anyone rebuilding or significantly upgrading their Pontiac 455 engine for racing. It's important to note that this assembly is not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified professional for specific installation procedures and compatibility with your existing engine components.
