Reply to "Bob Glidden Motor"

I forgot a few things. To make that big-bore block even more irreplaceable, Glidden started with rare "X" series thickwalled race blocks, not an over-the-counter 351C. I've never seen one but they're supposed to be similar to thickwalled Aussie blocks with no weight-saving sculpturing in the main supports nor pan rails. Duplicating the good stuff in a regular 351-C block is almost guaranteed to break the stock block in two horizontally at the weak spots near the main supports, from block flex. If possible, you might check to see what the casting numbers are on the block & heads.
