Decked DZ 302

[markinnaples]

So, I am pulling out the DZ 302 from my Camaro to replace it with a 383 or 406. I have a couple people interested in buying it, but I'm not sure what they're worth. Unfortunately, the block was decked BITD when they were racing it the stamping is gone, and I've tried to pull the numbers up with acid but they must have cut too much material off.
Now, I've read that some guys are buying them even if they've been decked and stamping them with their own numbers to fake a matching numbers Z, which, obviously, I'm not a fan of but once I sell it I will have no more control of it.

Anyone know a decked DZ short block will bring these days with one bad oil ring? How about if I sell the short block with the camel hump heads as well? Just not sure what's a fair price in today's market.
