Where could I find a complete wiring harness for a 1977 Dodge B100 van that I could put a 440 in? I'm slowly trying to rebuild this box to new condition so I can go to car shows in style.

Unfortunately there aren't to many places that make reproduction harnesses for the older trucks and vans. Your best bet is to try and find someone in your area that is good with fabricating electrical harnesses and have them try and make one for you. You can purchase a CD version of the shop manual from places like Moparmanuals.com that shows the wiring diagram for the vehicle and that will help them with the information they need to make something up.
