Eagle Pontiac 400 4.250in Crank 6.800in I-Beam Rods -6cc Flat Top 4.185in Pistons Rotating Assembly

Eagle is well-known for making strong internal engine components, and this Pro Street rotating assembly is a prime example of their work for Pontiac 400 engines. If you're building a naturally-aspirated racing engine, this assembly is designed to handle the demands of that kind of performance. It's a complete package that brings together all the critical rotating parts you need to get your engine built.

At the heart of this assembly is a 4.250-inch forged 4340 crankshaft, chosen for its durability and ability to withstand high stress. Paired with it are 6.800-inch 4340 I-beam connecting rods, which are secured with 7/16-inch ARP 8740 bolts – a name you can trust for reliable fastening under pressure. The pistons are forged 4032 aluminum flat-tops from Mahle, featuring a -6cc dish to help achieve your desired compression ratio, and they come with plasma-moly file-fit rings for a good seal. To ensure smooth operation and longevity, the assembly includes King XP rod and main bearings, known for their robust performance.

This rotating assembly is a significant step towards a powerful, naturally-aspirated racing engine. Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and break-in procedures to ensure optimal performance and durability.
