It seems most here think 600 hp is the limit for these blocks. It's kind of a mute point for me as I am staying between 500-600 hp. Thanks for your comment.
When I rebuilt that block the third time I usually just hone my blocks with a dingle berry hone. That block was so bad I wore out two sets of stones on my stone hone. Then I got out my dingle berry hone. When the rod broke it put a small divot on the bottom of the one cylinder so o threw it on my scrap pile. I don’t run them past .040 and I don’t think that block would have clean up at .040. So on the scrap pile it went. One of our members wanted it and I said he could have it but he never showed up. It was tubed for the oiling system and everything. Oh well it’s scraped.
