The rods were resized but I'd think that if the one rod that spun the bearing was too far gone to clean up within a few thousands, he would have told me and used another rod.
I thought they ground a few thousandths from the mating surface of the rod cap then bolted them back on and bored them to size?
Typically resizing rods you cut less than .005 off the rod.... Early 340 pistons are usually .020+ above deck... If the block gets line bored the crank moves up a similar amount...
