When you're building a Chevy 350 for serious naturally-aspirated racing, starting with a balanced rotating assembly like this one from Eagle can save you a lot of time and ensure a solid foundation. What you get in this kit is a fully balanced assembly featuring a forged 4340 crankshaft with a 3.480-inch stroke, paired with 5.700-inch long 4340 I-beam connecting rods. These rods are secured with 7/16-inch ARP 8740 bolts, known for their strength and reliability under high stress.

The pistons included are forged 4032 Icon flat-tops, each with a -3.7cc dish to help achieve your desired compression ratio, and they're sized for a 4.040-inch bore. This assembly also comes with plasma-moly standard gap rings, which are a popular choice for performance builds, and King XP rod and main bearings.
