David,
Thanks for the information. I've heard that the 69-71 blocks have a higher nickel content and what you're saying seems to bear that out. My '71 block has very little wear in the cylinders. It will obviously need more than a hone job, but should clean up with probably a .030 overbore. The one I have now has a .040 with no apparent problems.
My reason for asking about the max overbore is that this engine apparently sat for quite some time and has one deep rust pit in the cylinder. I'm surprised there was not more rust (sat out in the open for who knows how many years), perhaps it's low rust can be attributed to the high nickel content. Who Knows??
Thanks again,
auto10x
Bill
