About this part

Product Details

This Eagle Pro Street rotating assembly gives you the core components needed to rebuild or upgrade your Chevy 327 small journal engine. Inside this package, you'll find a 3.250-inch forged 4340 crankshaft, designed for strength and durability. It's paired with 5.700-inch I-beam connecting rods, which come equipped with 3/8-inch ARP 8740 bolts for a secure and reliable connection. The assembly also includes forged 4032 Mahle pistons with a 5cc dome, ready to be fitted with the included plasma-moly file-fit piston rings. To complete the package, King XP rod and main bearings are provided, ensuring smooth operation and proper oil clearance.

This rotating assembly is specifically built for naturally-aspirated racing applications, meaning it's intended for engines that don't use a turbocharger or supercharger. The use of a forged 4340 crankshaft and forged 4032 Mahle pistons indicates a well-built component set designed to handle the stresses of performance use. The file-fit piston rings allow for precise gap setting, which is crucial for optimal sealing and performance in a racing engine. ARP bolts are a well-known name in high-strength fasteners, adding to the overall robustness of the connecting rod assembly.

When installing this assembly, remember that the piston rings are file-fit, meaning you'll need to carefully measure and adjust the end gap to match your specific cylinder bore dimensions and intended use. This step is critical for engine longevity and performance. Please note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. Always refer to the manufacturer's detailed installation instructions for proper assembly and break-in procedures.
