That is interesting, things must have changed, I hadn't thought of that.
I know back in my drag racing days, one of the advantages of putting a 'glide in my Mopar (other than the tranny brake
) was that it only took about 48 hp to run it, and the 727 took about a 100.
I am sure torque converter technology has helped a lot with the gas mileage and the efficiency situation as well. The early "lock up" converters were a real problem source, but I haven't heard anything about them in years now.
