Hi, Gas Patch.
From Chrisco's chart, there apparently would not be a lot of difference. I have operated a couple AC DD's and they were generally reckoned to be around 8 long tons, give or take a bit - a long ton is 2,240 # - so possibly the DD might be slightly heavier by around maybe 1,600 - 1,800 #.
Hope this helps.
Model DD Allis 1961-1971 weight 9359# has D-262 engine(buda Diesel) 58HP
