They sounded great compared to the Cummins/Volvo motors that replace them now but they did belch smoke. If Rolls-Royce/MTU and Daimler wanted to, they could have kept building the original GM Diesel design.
The first generation of exhaust aftertreatment CARB mandated on transit buses and trash trucks gave out a small pull of smoke on acceleration.
That's interesting because a lot of old railroad equipment in service today uses screamin detroits and nearly all smoke very little if at all. I ran a piece of equipment with a 4-71 and it was under powered for the application so it was almost constantly under severe load. It smoked worse than any other detroit I saw but it was extremely slight. That engine was so loud standing next to it it sounded like it would never stay together.
I also saw a 4-71T in action and it didn't smoke either. I had no idea they had two strokes in buses.
As for rollin' coal it's pathetic. I think it makes it easy to spot the retarded grown [censored] kids. Where I moved now there are a ton of red necks who all drive trucks, the bigger the better. More than 3/4s of them can't justify owning and driving a truck with the way they use it but hey they got a big truck. I wonder if it has to do with the extremely high rates of inbreeding and low iq.
