Eagle is well-known for building strong engine components, and this Pro Street rotating assembly is a prime example of their work for Chevy 327 Small Journal engines. If you're building a naturally-aspirated racing engine, this assembly is designed to handle the demands of the track.

This assembly starts with a 3.250-inch forged 4340 crankshaft, a material chosen for its strength and durability under high stress. It's paired with 5.700-inch I-beam connecting rods that feature 3/8-inch ARP 8740 bolts, known for their reliability in performance applications. The pistons are forged 2618 aluminum from ICON, a popular choice for their ability to withstand high temperatures and pressures, and they come with plasma-moly file-fit rings for a good seal. This assembly also includes King XP rod and main bearings, which offer solid performance for racing use. The mains are 2.300 inches, and the pistons are 4.000 inches with a 6.3cc dome volume, designed to work together for optimal combustion in a naturally-aspirated setup.

When putting together a performance engine, the rotating assembly is the heart of it all. This Eagle Pro Street assembly gives you the core components you need to build a robust, naturally-aspirated racing engine. Please note that this assembly is not CARB approved and cannot be shipped to California. Always refer to manufacturer instructions for proper installation and break-in procedures.
