Absolutely I would use it. The 65-66 blocks from what I have read many years ago in the defunt Super Ford were the strongest production blocks. That's an old wive's tale about the length of the bores being shorter. This topic has been posted many, many times here. No meaningful difference. Again, what I have read on this, is that apparently on the orginal drawings when designed it did spec shorter but when they were produced, it was no longer the case. All basically the same.
