That front 44 will fight admirably, but won't live for very long with the 44"+ tires I'm assuming would be 'appropriate' for a truck with a 25 inch lift. I'm thinking of that moment when you're pegged at 4000rpm in the bog, spinning the tires, and then all of a sudden the front tires grab on relatively solid ground on the far side of the hole...

When you say 'mud truck' I think big lift, big tires, big HP - as in the kind of big tires and big HP that are probably pushing the limits of a Dana 60 while being thrashed through a bog. I think the bare minimum for a mud truck would be an Eaton or 14Bff in the back and a Dana 60 in the front.
