Got it all torn down.it is a 2 bolt block.stock crank turned .010 on rods and mains.pistons and rods all look good and pins move freely..main bearings have alittle grooving and one rod bearing lock was ground off.the kotor also had low oil pressure at idle after warmed up.less then 5 psi.still not sure what the rapping noise was.
