    Thanks for adding to the collection sbc! What do you think the story is with the CHS on the block like that?

    I don't know, I bought this car unmolested and did a ground up resto on it, when I pulled the motor CHS was clearly marked on the side of the block.
    I assume that was done at the factory assembly.
    Heres the block stamping.

    No I have not, that is precisely why I keep this thread going. I believe some of the literature that folks on this board subscribe too is wrong in print. And those errors get passed along on the internet when those publications are copied to websites.
