My 3-29-69 383 GTS has only 8 digits, and so does my Feb built M-Code GTS. I just bought an original Mr. Norms 440 block from a GSS and it has 8 digits on the bellhousing rail. I took pictures today that I will post to show what a real 68 block looks like!

The funny thing about science is that if you change one miniscule parameter you change the entire outcome to the way you want it.
