Cool picture.

Most, if not all of those trucks should have 6-71's.

Even though some say no, idling them seems to be OK.

But not 6V-53's. A petroleum company I knew that ran 6V-53 Oil Trucks used to start them about 4 in the morning and let them idle till the drivers came in around 7. Just about every one eventually developed engine problems. A 53 seems to have good Oil Pressure when it's cold, but drops off once it's warmed up. Same with my 2-53. Shows great pressure cold, but low when warm. I try to avoid idling it any more than 5 minutes.

Hearing all those Detroit's all idling at the same time must have sounded pretty cool though.
