Eagle Chevy 350 3.750in Crank 5.700in I-Beam Rods -7cc Flat Top 4.000in Pistons Balanced Assembly

If you're rebuilding a Chevy 350 for street use, especially with a focus on naturally aspirated performance on pump gas, a balanced rotating assembly like this one from Eagle is a smart way to go. It bundles all the critical rotating components together, ensuring they're balanced as a set for smoother operation and reduced vibration. This takes a lot of the guesswork and precision balancing work out of your engine build.

This assembly features a 3.750-inch cast crankshaft, paired with 5.700-inch I-beam connecting rods. These rods are secured with 3/8-inch ARP 8740 bolts, known for their strength and reliability. The pistons are hypereutectic KB flat tops with a -7cc dish, designed for a 4.000-inch bore, and come with plasma-moly standard gap rings. To top it off, it includes King SI rod and main bearings, which are well-regarded for their performance in street applications.

Because this assembly is pre-balanced from the factory, it simplifies the engine building process considerably. You'll want to confirm fitment for your specific Chevy 350 application, as this assembly is intended for naturally aspirated, pump gas street vehicles and is not CARB approved. It's a solid foundation for a reliable street engine build.
