Is there any one single thing that you can look at on an MC engine to determine if it is mc1 or mc2?]

I suppose you can look for the 2 knock sensors if the engine is installed in the car.

Except for engine numbers whcih one could look up I suppose, I don't believe there are any other external differences.  I wouldn't be able to tell the difference.  We are talking about the engine itself - there are other clues if you have the car, such as ECU having MAC-14 on it and a few others.
