5.0 is a different engine family than the 351m/400. Not a direct swap, you would have to swap trannies if it's a automatic or swap bellhousings if it's a manual. And the manual bellhousing swap can be a can of worms.

If you do not have inspections, you could swap the 5.0 over to a carb. It would be a little bit of work, the gas tanks/fuel system would have to be modified also. But under all that junk is a good old 302 that will accept a intake and carb.

Do you have inspections? We don't in Florida per se, but there is a law on the books about not modifying after sometime in the 70s, so it could be a problem. What yr is the truck?

Never heard of a factory 2.5 inch lift on a f150. What type of lift does it have, suspension? I would not put it past some dealer somewhere to have put a lift on it and made it a promotional truck of some sort.
The factory doesn't like lifts generally, the center of gravity becomes too high. Even the few times the factory did have a special "off-road" version(I think some of the little Rangers could be had like this) it was only 1 inch.

Put a carb./intake on it, switch ignition systems and enjoy. I swapped a carbed 351W for a problem plagued '89 5.0L EFI and like it a lot.
Removing the high pressure fuel pump on the frame rail and using a pressure regulator in conjunction with the low pressure in-tank pump should solve the fuel issue. (or put on a mechanical pump and replace the in-tank pump with a drop tube)

Have a divorced transfer case and in cab fuel tank. The front could have either 5 or optional 6 leaf springs with an optional H/D leaf.

This truck also has a handling package 4 shocks up front the lift is 2.5 inch blocks under leaves also factory installed overload springs stops are hot revited to frame somewhere a few years ago I found apparently these were all options you could order. Truck sits like a 250 could easily fit 32 11.50s on it as it sits
While you could put large tires on it, I would not recommend it without a gearing change. The little 302 doesn't have much torque to pull around really large tires. And anything much over 31X9.5 inch tires are going to rub the radius arms in a tight turn. Been there, done that.
