My understanding when talking to a former NCRS Chairperson who worked at GM was that they were cast in batches of 300 and had poresity or casting problems with a large proportion of the blocks.
Now I have no idea how long it takes to cast a block, (anyone know ????) but if casting this batch took a couple of days, When this was done did they change the casting date of the batch or leave it with the first days casting date. They changed the casting number each time, but did they change dates ??
Considering only 71 went into cars, the above still gives us a lot of blocks.
Now considering how hard it was for GM to sell these cars, I don't think they were interested in putting a big stock of these in storage ....just in case someone had a lazy couple of grand and dreams of winning Le Mans.
If we could work out how many batches were cast we might have an idea of the number of blocks made. (ask that question everywhere I go )
Considering what collectors pay for the cars I find it interesting that we don't know more about the engines.
Thanks for the reply anyway.
