Are there any differences in appearance, or engine or what?

Since F40s didn't appear until around 1976, surely nobody thinks they lacked modular controls? So ... what is an F40PH-2, anyway?

And 3000 horsepower is repeated in the general information table and on the performance curves.Did they (order #766062) have the exhaust silencer? If I remember correctly we had to subtract horse power during the HP calc for the silencer. I don't remember the value of subtraction, and order #766062 was before my time in test department.
In the same bunch of stuff is a list showing EMD locomotive order #766062 for the Regional Transportation Authority (Metra) for units number 100 through 127 rated at 3200 horsepower when delivered and they are listed as F40PH, not F40PH-2.
Hmmmm.....
