I use two of the same blocks. I have had one since 1991 and it is now 35 0ver and I bought a brand new, never touched mate to it recently for 1500 canadian. Your block has less life in it so maybe this will help you make an offer

just bought 2 30 over, fresh bore 6 months ago for 1100ea. Definately less than 1000.00, as aftermarket will cost around 1800.00, these are nice blocks and much beefier than gen 6.Good luck

.060 over what? If you are talking 4.560, the walls are very thin, and at there limit. The Gen 4 Bowtie was only designed to be bored to 4.50 with a .030 overbore. When GM came out with the Gen V bowtie, they increased the cylinder bore thickness to allow a 4.60 bore. I have seen two Gen 4 bowties at 4.600 bore and the walls were paper thin. They are real old blocks, I would not give over $500 each for them. Personally, I would not want them. I would buy new 502 blocks before that. Merlins or Darts after that. A 502 block has thicker cylinder walls than the Gen 4 bowtie. The decks have larger water passages.
