So the story goes my customer purchased a used race motor and installed it into his car despite my warning. After getting it in and checking the compression he realized something was wrong. The best # he got was 120 in number 3 the rest were down to. The block came to me and I tore it apart. The block has 020 over Wiseco hd pistons and the eagle crank and rods with the upgraded arp hardware. The rings were gapped accordingly, and ptw was over .004. For the record the head was in perfect shape. What I did find was very tiny vertical scratches in each of the bores, enough to catch a finger nail. I also noticed that the main bearing have a blueish coloration to them. Is this normal bearing wear? The crank is in perfect shape. What you guys think? He brought the block to the machinist to see if it could be honed out. The machinist said he was able to get them out within spec. I plan on remeasuring when I get the block back
