If the block doesn't cost $999.99 or less, come absolutely perfect for your particular combo and have every bell and whistle I doubt he'll sell 10 blocks to the general public.
The Chrysler people are the cheapest people out there. They can run 10's one stock block and that's good enough.
If they get made, and made for more than 1 production run I'd be stunned.
I for one have no problem paying for a good block so were not all cheap a$$ like you think
