MM is a 66 buick 300 engine. It was a low compeession (7.6:1) 2bbl export engine.
I have a 1966 buick Skylark and its engine has a strange code I'll live the picture if any one can help. I live in Guatemala and here nobody knows anything about my Buick. I think it is a 300 ci but it seems to be a code M M??.
Thank you very much...
