Welcome!!!
First, we will also need to know gear ratio and what type of tranny. Here is a post from awhile back that answers your question.
towing capacity of 94 F-350 IDI turbo
Next time you can save yourself time by doing a search. Most times general questions like this can be found using the search function at the top of this page. Click on search and hit ADVANCED search to find stuff specifically for the IDI's.
Happy Hauling
Thad
