ALUMINUM BLOCK 0-326711 Value ???? Come In WHAT ??

[DRIVER155]

Hey Steve , I wondered if that block could be actually finished myself . I did some more research on the block i'm lookin at and it was definately a prototype block ....says all "0-" blocks were and production was supposedly for over the counter sales , but GM made sure that didn't happen because they wanted these blocks in a select fews hands . Where would you try to sell this rare piece and whom to (EBAY) ? Sounds as if this block is more rare than the actual ZL1 , but i'm at a loss as to the TRUE VALUE also . Thanks , Richard
