    Description

    CE 3963512 512 Big Block Chevy BBC 427 454 4 Bolt Main Block D-6-71 (Small Crack)
    Cleaned and checked for cracks. Found one very small crack in one of the freeze plug holes. See pic # 12. It did not leak when we ran but it's there and can be spot welded repaired. Number 7 cylinder has a sleeve installed and cylinders are 4.28 (.030 over). Cylinders are nice with no ridge. Never decked and pad stamp still there but cant make it out. Can be used in a 1969-70 muscle car as a warranty replacement block to be period correct like Copo or LS6.
    Part # 3963512  Date D-6-71
