Forged 4340 steel is the foundation of this balanced rotating assembly, featuring a 3.766-inch stroke crankshaft designed for Chevy 427 applications. This assembly is built for naturally-aspirated racing use, offering a solid starting point for a performance engine build. The use of forged materials means it's well-suited to handle the stresses of higher RPM and increased cylinder pressures common in racing environments.

Complementing the crankshaft are 6.135-inch long I-beam connecting rods, also made from strong 4340 steel. These rods are secured with 7/16-inch ARP 8740 bolts, known for their reliability in performance applications. The pistons are forged 4032 aluminum from Wiseco, featuring a 21cc dome and a 4.280-inch bore size. They come with plasma-moly file-fit rings, allowing for precise gap setting to match your specific engine build and maximize performance. King XP rod and main bearings are included to ensure smooth operation and durability for the rotating assembly.

This balanced assembly is intended for performance builds where reliability and strength are paramount. Please note that this assembly is not CARB approved and cannot be shipped to California. It also carries a Prop 65 warning.
