About this part

Product Details

This Eagle Specialties rotating assembly is built around a 3.480-inch stroke crankshaft, a solid foundation for a performance-oriented Chevy LT1 350 build. The H-beam connecting rods measure 5.700 inches long, chosen for their strength and ability to handle increased cylinder pressures. Paired with these are 4.000-inch bore pistons featuring a -21cc dish volume, which helps achieve a desired compression ratio when combined with your cylinder heads.

Eagle Specialties is known for producing well-built internal engine components, and this assembly is no exception. The H-beam rods are a popular choice for many performance applications due to their robust design and reliability under stress. The crankshaft is forged, offering superior strength and durability compared to cast alternatives, making it suitable for engines that will see regular use and higher RPMs. This complete package simplifies the process of sourcing critical rotating components, ensuring they are balanced and designed to work together as a system.

When rebuilding or upgrading your LT1 350, a balanced rotating assembly is crucial for smooth operation and longevity. This kit includes the essential pieces to get your engine's bottom end assembled. Remember that this assembly is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's detailed specifications and installation guidelines for proper assembly and break-in procedures.
