    454 rebuild cost.

    I'm about to tear down the big block for my 76 c20 and see where the knock I am having is coming from. How much does it cost to have a stock rebuild done. I realize that it's different everywhere and depends on how much machining has to be done. Just trying to get a idea. Thanks in advance.
