With 185hp and 385 ft lbs of torque, it does not move a lot of thing fast. BUT, if you can keep it from overheating, you will get there! If it does not have the post 97 dual t-stat, hi flow waterpump, larger fan, do so, that is at least 10-20F on hills pulling. Altho with a 93, I believe that is the manual injection pump vs the later electronic one, so the overheating issue is not as great.
If you want to rebuild it, it is a much more tweakable motor than the 94+ electronic ones.
The 4l80 is the other weak point. There are some mods you can do to get a stronger trans. BUT, it is steal a poor towing choice as first is a tall gear ratio.
Max gcwr is 14500 for that motor. Not a big trailer if the truck weighs 5500-7000 lbs for a reg cab vs crew cab. My 96 sw CC weighed 6600 lbs. I pulled upwards of 12K with it. No not as fast as my 05 duramax, but I got there. I also had a 5 sp manual, which in reality, is the better trans behind that motor, even tho before 97, the manual was rated 2000 lbs less than the auto......
