    Default Sonic Numbers

    I had a block sonic checked a few years ago. They wrote on the block so I transferred the numbers to paper.
    Mercury marine 330hp 454 casting 10069286 1989
    Ed Hale in San Diego did the sonic work. I was planning a 8-71 blown 496 for my car. He said that the numbers were sufficient. See pic #1 thinnest was .139 non thrust and .143 thrust.

    I just had a different block done and OMG is it thicker. Pic #2
    it is a 1975 casting 364776
    It is about double the thickness!

    Is there really this much difference in the castings?
    Has anyone else had a block sonic checked? Do you have the sheet that you can post?
    I thought that the marine block would be better, but.............

    The second block is a earlier 427 truck block. Yes, they are that much thicker. So is the deck.
