Eagle Chevy Big Block 2pc Seal Pro Street Rotating Assemblies

Pro Street Rotating Assemblies are designed for Chevy 454 blocks with a 2-piece rear main seal. These are Eagle's most affordable, all-forged assemblies and recommended for use in pump-gas competition engines NOT using power adders. Kits include an Eagle Forged 4140 Steel Crankshaft; Eagle "FSI" Forged 4340 I-Beam Rods with 7/16'' ARP 8740 rod bolts, .990'' pin size, Alignment sleeves for precise cap location, Silicon bronze pin bushings; Mahle Forged Pistons and Plasma-Moly Rings; and Clevite or King Bearings.

Features:

Forged 4140 Steel Crankshaft
"FSI" Forged 4340 I-Beam Rods with 7/16'' ARP 8740 Rod Bolts
Forged Mahle Pistons with .990'' Pin Size

Notes:

Assembly 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.
All kits are designed for internal balance.
Chevy 454 standard bore size is 4.250''. Kits are available in .030'', .060'', .070'', and .100'' oversizes.
Eagle Specialty Products reserves the right to substitute pistons due to availability.
