im pretty sure my motor is bored .060, but is there anyway to know? like when its rebuilt, is there any markings that ar eput on the block? like i said, im pretty sure im bored .060, im just hoping im not bored that much, i want to confirm it.

 

Usually the tops of the pistons are maked with the overbore amount. Or you can measure the bore and compare it to a stock bore. You will need to pull a head off to find out though.
