    hello, looking for help trying to find out what 455 old engine i have.
    on the front of the block above timing cover there is a
    396021-F stamped into the block the heads have a Ga stamped in them
    and on the back by the dist area there is a 157 and right under the dist it looks like a CFD6 or CF06
    any help would be great
    thanks

    Looks like you have a 455 block with 455 heads!
    I couldn't resist....

    If I am remembering correctly.
    The F blocks are late 60's to early 71 blocks. Rumored to have higher nickel content. Supposedly the higher nickel content makes for a strongr block.
    Ga Head... Later early 70's emissions head...
    I am going off of memory. Check realoldspower or another site like that...
