About this part

Product Details

When you're building a serious performance engine, especially one intended for racing, nitrous, or forced induction, you need a rotating assembly that can handle the stress. This Eagle Chevrolet 436 Competition Rotating Assembly is built for those demanding applications. It comes with everything you need to get your engine's core rotating components squared away: a forged 4340 steel crankshaft with a 4.000-inch stroke, 6.000-inch H-beam connecting rods that are clearanced for stroker applications, and 7/16-inch ARP 2000 bolts to secure them. You also get forged 4032 aluminum pistons from Mahle, featuring an inverted dome design with a -20cc dish and a 4.165-inch bore size, along with plasma-moly file-fit piston rings. To top it off, this assembly includes King XP rod and main bearings, known for their robust performance under pressure.

This assembly is designed for Chevy 400 and 350 main applications, providing a solid foundation for a high-performance build. The use of forged 4340 steel for the crankshaft and H-beam connecting rods means you're getting components that are significantly stronger and more durable than cast alternatives, essential for handling the increased cylinder pressures and forces found in racing engines. The Mahle pistons are also forged, offering excellent strength-to-weight ratio, and the -20cc dish combined with the 4.165-inch bore will help achieve your desired compression ratio when paired with appropriate cylinder heads. The inclusion of ARP 2000 bolts signifies a commitment to reliable fastening under extreme loads, and the King XP bearings are a popular choice for their ability to maintain oil film and withstand heavy loads.

It's important to note that this assembly is not CARB approved and cannot be shipped to California due to emissions regulations. When installing this rotating assembly, ensure you follow the manufacturer's detailed instructions for proper clearance checks, bearing installation, and ring gapping to achieve optimal performance and longevity. This is a well-built package for anyone serious about building a powerful and reliable racing engine.
