Bergy - Thank you for your personal experience and insight into the foundry operation...awesome info!
Aside from the casting core variations, could you comment on M-coded blocks, (instead of the traditional casting date). Specifically, what types of changes would dictate creating M-coded blocks and typically how many were run for evaluation? I've been fortunate (unfortunate??) to have had two M-coded 010 blocks...one in a 70 Z28 and one in a '72 Z28.
