Gearing to go with a 393 stroker?

I am building up a 393 stroker to drop into eather a Bronco or a single cab, short bed, F-150. I am going to raise up the suspension enough to fit eather 44"-54" super swamper boggers on the truck. With that set up I was wondering what transmission gearing, rear end, and front diff. gearing set up would be best? I plan on replacing the stock axles with bigger beefer ones, I'm not too sure on what to use for that eather (the front axle is deffanatly going to be solid). I just don't want anything to snap between the enging and the tires when I'm rompin' on it in thick mud. I am primarly gong to use the truck for mud bogging. With those big tires I was also wondering if I should consider axle extensions for better tire clearance and a wider wheel base?
