Reading from my Cummins B3.9 shop manual, in front of me;
4B3.9 679#
4BT3.9 705#
4BTA3.9 725#
Weights are less Flywheel and electrical components
In my Cummins conversions on the Power Wagon and WC-53 Carryall, I bought new springs from Steven Flower. He had springs made with a 2" extra lift. I then had a local spring shop add 3 more leafs to carry the extra weight. The Cummins oil Pans were notched 2.0"x2.0" on the 3rd member side for clearance on compression. The ride was good
as was carrying capacity. My M37 also had a 2.0" added arch on the springs with 3 extra leafs, oil pan was also notched. The W300 Power Giant conversion did not need any lift or extra spring leafs added, the Power Giant
front suspension was a brute, nor did it need a oil pan notch, rather turning the oil pan around and going to front sump solved all clearance issues.
Go to the archives, search on Steven Flower, Springs. I dont know if Steve still has or sells springs. If he does, he had good springs made, no issues and Steve is a good guy to deal with.
