Quote: Are those rods easy to resize? I've always played it safe with rebuild of engines with spun bearings, opting to have the rods resized. If it was only a main bearing that spun, it still may be wise to "mike" the big ends of the rods to ensure their size.
I'm going to go through everything and see where they setup the bearing clearances. Though I found the symptoms of the problem, I'm not confident I found the source yet. When I talked to Arrow, there were no special machining operations for the aluminum block that differed from other engines, I was happy to hear that. I wish I still had access to machine shop equipment like I did in San Jose. I had to buy a dial bore gauge so I can check the rods, mains etc. But I don't mind buying tools....
