Skip it, find what ever the Bronco came equiped with. If it has a 5.0 or a 5.8 those engines really wake up with long tube header and a cam.

A 4.6 swap would be a very nice swap as the early Bronco is light. However, the early bronco has a very small engine compartment and about the only V8 that will fit is the smallblock with the 8.2" deck height. The 351W will bolt in but the hood has to be modified for clearance. The 4.6 with 2, 3, or 4 valve per cylinder is a very wide engine and I think serious modifications would have to be made. It's not worth the hassle.
I would suggest a stock fuel injected 5.0 as a very nice fit and one that if you keep the EEC-IV with Mass Air flow sensor it shouldn't be that difficult to wire up. 215 or so hp in that little vehicle will be plenty.

That's what I'd do.
