Last one I did was about 60# and would have easily fed pulled pork to 50-60 folks (had 35 for luncheon and only ate 1/2 the pig). I plan on 60-75 minutes per 10 pounds (dressed).
Here is my last pig cook, you can see in the first few pictures there is plenty of room in a 120 gallon offset for a larger hog.
I have a 120 gallon as well (really jonesing for a 250 but that's a different story) and have done a 80 pounder, head-on and racer style. It took about 12 hours at ~250. Got great results and feed about 55 guys from the cigar shop, big eaters.
The only thing I would have done differently would have been to add something (cabbage or small butts or chuckies) under the cavity to protect the loins/ribs.
