A somewhat expensive, but more ethical way of salvaging a scarce block is installing 3/32" wall sleeves in all the cylinders to bring it back to standard bore. It helps if you happen to have a boring bar like I do, so the only real cost is for 8 sleeves. Paying a machine shop to install them increases the cost exponentially. Some Camaro restorer might be willing to pay you good money for that block, so don't scrap it.
