Not many Z10's. Depends on who you talk to. I have heard anywhere from 188 to 700. Talk to Kurt or Mark at CRG.

Really not many big block Z10's. I have seen at least 10 Z10's over the years, and only one big block.
In fact, we had four at one time in a local car show one year, but no big blocks.

I have a buddy that has a very nice small block with factory air. PM me if you want his email, as I am pretty sure he knows more than I do about these cars.

Just a thought. Even though they are comparatively rare, it is still all about supply and demand. The Z10 (and Z11 for that matter) demand seems to ebb and flow a little more than the rest of the first gen market. JMO.
