I am taking the block to the shop tomorrow or next day. They called me today and said the balance was off on the crank. They said it wasn't a lot but it was off..He said just one end. He never said anything about taper but did suggest I use an "X" bearing.I did mention the taper issue to him when I gave it to him..regardless he is going to measure the block and the rest of the rotating assembly to insure all is correct.
Just a question..how does a brand new block end up with taper on the main bores? The crank I can understand but how does a block get line bored tapered? Not arguing just asking.
