Well Marshall, you inspired me. Tonight I took my 84 SD out for a stroll. The car has a full tank of fuel, 2 people on board and 212,000 miles on the engine. The ALDA is still factory sealed. Level road. Ambient temperature of 78 degrees F. I did four runs 0-60 and averaged 14.8 seconds. I don't have a baseline to compare, since I did not do any 0-60 runs with the 3.07. I think this is a pretty respectable time. What do you think?
