1971 911T cylinders
I am rebuilding a 1971 911T motor that has been sitting in my garage for a while and have decided to throw it in a car that I have just acquired....
The motor has the cast iron barrels. Upon teardown I have found that 2 of them need replacing. Aside from measuring, is there a way to visually differentiate the Group 5 barrels from the Group 6 barrels? barrel = cylinder T |

Unlike all of the aluminum cylinders used by Porsche, the cast iron cylinders were ink stamped with the ht group marking. On most used cylinders, the markings are long gone.
You will have to measure the cylinder ht to determine the size if the ink stamping is no longer visible.
