What C4 is saying, is it doesn't need bored. And I'd tend to agree, but if your kit you're buying comes with new pistons, then yes, I'd go ahead and go over bore. That .005 you're talking about it probably needed, or are you talking out of spec? See I have problmes understanding you at time. Here is an example, If you are not .030 over, so lets say you have X.030 pistons. If you have X.035 as a measurement, then for god sakes, call it brand new with a rering motor cuz you will not get a X.030 piston to move in a X.030 cylinder. That would be to tight and you'd likley break your ring groove landings off the pistons. Another good way to measure a block cylinder is to use your rings. Put the original rings in the bore. Push them down square with a piston top to make sure they are square in the cylinder. Then measure the gap. That will give you a clue of how much the rings and cylinder wore. If it's not much, rering the bitch and be done. And don't waste money on new pistons either. Also when measuring this way with rings, only go down about 1/2 inch in the cylinder. That is where you get most of the wear. That is called the Ridge.
Am I the only one not following here?
