Can anybody explain or show a link to explain the various date code stamps and symbols that were used to show a service block versus a production block on an FE (specifically a 427 SO)?
I've seen a couple pics lately, and have seen both an O with two dots above it, and another with an I or and l with two dots above it. Are these both service blocks? What is the difference between the two?
They don't seem to have a 7 or 8 for the year as the first digit. They have this weirdness with the dots, and I seem to remember service block talk but can't remember the whole story..
Royce? Jim? Anybody?
Thanks!
