66 427 Block Casting Number
Thanks In Advance For Any Info Given. What Is The Correct Block Casting Number For A 66 427 390 Hp Block. Should It Be A 2 Or 4 Bolt. My Motor Has Been Milled So I Cant Refer To The Stamped Code To Verify Originality.
Thanks Again

According to my NCRS book:
'66 427/390 bocks should have casting number 3869942.
An early '66 BB could possibly have 3855961.
A late '66 BB could possibly have 3904351.
390hp were 2 bolt, at least in '67.
