If you're building a naturally-aspirated racing engine for a Chevy 400, this assembly is designed to handle the demands of the track.

At the core of this assembly is a 3.750-inch forged 4340 crankshaft, featuring 350 main journal size for compatibility with many popular Chevy blocks. Paired with this are 6.000-inch I-beam connecting rods, also made from strong 4340 material, and secured with 7/16-inch ARP 8740 bolts for reliable clamping force under stress. The pistons are forged 4032 DSS units with an inverted dome design, measuring 4.155 inches in bore size and featuring a -16cc dish to help achieve your desired compression ratio. They come with plasma-moly file-fit rings, which allow for precise gap setting to match your engine's specific needs and ensure good sealing. To complete the package, King XP rod and main bearings are included, offering excellent durability and performance for your build.
