Very interesting information

I did the Perfect Circle "Doctor of Motors" thing in 1957 and I still have the certificate for it somewhere. I still use the information.

the perfect circle course is the first one I did. It explains the the type of low tension rings GM uses.

Thanks for the info. I am actually learning more (including "Clevite 77" history).
