c126 AMG models

Servus, I have some questions about the 560 SEC again. I have here in the attached picture a table of AMG. Now I would be interested in what is different at the AMG than at the normal 560s! So, camshaft, fan manifold, characteristic field change, larger bore, etc. The stroke is identical I think, but the rest will be different? Greeting MADE_IN_GERMANY
