: Ya RIGHT!
Back in 1997, I had a '69 Charger R/T with a 440 and 727. When I got it, it had been sitting for a long time, so all oils got changed. When I went to drain the 727, I got 5 quarts of fluid out of the converter alone, after the pan had been emptied! I also loosened up the valve body and slid out the accumulator, because you can get a lot more fluid out if you do that. I ended up refilling the transmission with almost as much fluid as the books say is the capacity. 17 pints or something like that. 8-1/2 quarts.
Also, when I get a new mopar and am going over it, I always take off the sheet metal shield that covers the converter. If the particular car requires it, I'll cut out the piece that goes under the starter mount and reuse that part. But the converter stays open. I think the extra airflow might help the converter stay a few degrees cooler, and it's just easier to get at everything that way.
