Eagle Chevy 350 1Pc 3.750in Crank 6.000in H-Beam -18cc 4.060in Pistons Balanced Assembly

If you're building a high-performance Chevy 350 engine for racing, especially with nitrous or forced induction, a balanced rotating assembly like this one from Eagle is a critical starting point. This assembly includes a forged 4340 crankshaft with a 3.750-inch stroke, 6.000-inch H-beam connecting rods, and Icon 4.060-inch forged pistons. Getting all these major rotating components balanced together from the start is key to a smooth-running, durable engine that can handle the stress of competition.

Eagle uses a forged 4340 steel crankshaft for strength, paired with robust 6.000-inch H-beam connecting rods secured by 7/16-inch ARP 8740 bolts. The included Icon pistons are forged 4032 aluminum with an -18cc inverted dome, designed to work with the chosen compression ratio and cylinder heads. They come with plasma-moly file-fit rings, meaning you can adjust the ring gap for your specific application, which is important for boosted or nitrous engines. King XP rod and main bearings are also included, offering solid lubrication and wear resistance for these high-stress components.

This is a complete, balanced assembly ready for installation into your engine block. Remember that this assembly is not CARB approved and cannot be shipped to California. You'll need to ensure all other components in your build are compatible and that you follow proper engine assembly procedures for optimal performance and longevity.
