      Performance Small Block Chevy Rotating Assemblies

      These rotating assemblies are designed for pre-1986 small block Chevy with 2-piece rear main seals. They offer affordable performance and reliability for engines making less than 500 horsepower. Kits include an Eagle Cast Steel Crankshaft; Eagle "SIR" I-Beam Rods; Silvolite Cast, SRP, or Mahle Forged Pistons; Hastings Rings; and Clevite or King Bearings. Kits are available with internal or external balance.

      Show MoreAssembly part numbers that begin with “B” are balanced by Eagle and require no additional balancing. Part numbers that do not begin with “B” are unbalanced assemblies and must be balanced by a qualified machine shop before use. Kits are available in a standard bore or .020 in., .030 in., .040 in., and .060 in. oversized. Eagle Specialty Products reserves the right to substitute pistons due to availability.
