Value of a Mega Block

I have a 440 Mega Block for sale locally. Best offer. I promised it to Reagle Dodge 1st. If he passes there are 3 others in line. So this is not a for sale thread. I am curious what they are going for at this time. The block is standard bore plus .030 it was sonic tested and is like new no other machine work was ever done. It has never been assembled and run since new. What would be a fair asking price for both parties. Again this is not a for sale thread, I have buyers locally.
