No, the block could not handle a .60 bore, because that's 600 thousandths of an inch or nearly 5/8 ths of an inch the way you have it written. Should have been written 0.060" (sixty thousandths of an inch). The zero on the left side of the decimal point tells you that you are dealing with less than a whole number. If you wrote it as .060", with no zero to the left of the decimal, then the reader could question whether or not you meant a fraction of an inch or whether you left off a whole number when you wrote it.
0.001" one thousandth of an inch.
0.0015" one and one half thousandths of an inch.
0.030" thirty thousandths of an inch.
0.060" sixty thousandths of an inch.
0.170" one hundred and seventy thousandths of an inch.
0.600" six hundred thousandths of an inch.
4.030" four inches and thirty thousandths of an inch.
You can't just decide to bore a block this size or that size without knowing how much meat there is in the cylinder walls. Specs will vary from builder to builder, but having a minimum 0.200" cylinder wall thickness on the major thrust face (the passenger side of the bore as viewed from the radiator) and 0.135" cylinder wall thickness on the minor thrust face (the driver's side of the bore as viewed from the radiator) after boring and honing would be acceptable to most builders I would think. Wall thickness is determined by "beeping" the walls with an ultrasonic instrument. Either rent a beeper and do it yourself or take the block to a shop that has a beeper and have them do it for you.

Ask Pat again. He's getting a little old and senile, so you have to keep after him.
