Eagle Chevy Small Block 1 Piece Rear Seal 383ci Rotating Assembly w/ .030 Bore 153 Tooth Flex Plate

This Eagle rotating assembly gives you the core components to build a strong 383 cubic inch small block Chevy engine. Inside this kit, you'll find a balanced 3.750-inch cast crankshaft, paired with 5.700-inch I-beam connecting rods that feature 3/8-inch ARP 8740 bolts. For the pistons, you get hypereutectic KB pistons with an inverted dome design, sized for a .030 inch overbore (4.030 inch bore diameter). The assembly also includes standard gap plasma-moly piston rings and King SI rod and main bearings to ensure proper lubrication and wear resistance.

This is a balanced assembly, meaning the crank, rods, and pistons are weighted to work together, which is crucial for smooth operation and longevity, especially in street applications. The hypereutectic pistons are a solid choice for pump gas, naturally aspirated street vehicles, offering good durability. The included 153-tooth flexplate means you have the essential piece to connect your engine to an automatic transmission.

This rotating assembly is intended for street use and is not CARB approved, so it cannot be shipped to California. It's a well-built foundation for a performance small block Chevy build, providing the essential rotating components ready for installation.
