Whoever the rebuilder was looks like a low quality outfit, the rods dont match because a rebuilder like this buys junk rod cores and matches up caps and bodies "close enuf" then cuts the caps and resizes the rod, I have seen this type rebuild be up to .020 short of a stock rod length and almost that much too long, combine the .020 short rod with a rebuilder piston that is .020 short to begin with and you have a problem. The discoloration is from excessive heat on the small end of the rod, heat is used to expand the rod "eye" so the pin will slip thru, then when cooled it has an interferance fit, if over heated this fit is not as good and a pin can slide over and groove the wall. Chevrolet had this problem with early high deck big blocks.
