If you hate FI, you woke up in the wrong century? Can any carbed vehicle run 100,000 miles without maintenance on the carb or some kind of adjustments? Stick with FI, it needs no adjustment and just plain works, thats why carbs were abandoned.
The answer is probably no. Ford often deliberately made certain carb and EFI manifold so that they won't interchange unless you make modifications. With mods it might be possible, I'm not familiar enough with the differences between those two engines.
But honestly, what do you hope to achieve, converting to carb will likely be expensive, and will probably result in less power and worse fuel economy unless you are very experienced with adjusting carbs.

I hate EFI as well, but sometimes it's the only choice.

The only people that hate EFI are the ones that don't understand it. Ford EEC-IV Fuel Injection is so simple that the only reason why you don't understand it is that you are too lazy and stubborn to learn it.
EFI is dirt simple. Start with the fuses and fusible links. Then move onto the real diagnostics.
An engine needs 3 basic components to run, whether it has carb or fuel injection:
Compression
Fuel
Spark
Does it have spark? No? Check for power at the coil - just like a carb vehicle. Then move to the distributor..
If it has spark, move onto fuel. Spray some starting fluid into the intake. Does it start up? If yes, check for fuel pressure at the rail. You can rent a fuel pressure tester from autozone (should be around 39 PSI), or just poke the schraeder valve with something and see if fuel sprays out.
If it doesn't start up on starting fluid, and has spark, move on to the engine itself. Are the plug wires on correctly? Are the sparkplugs fouled/broken? If the plugs and wires are good, then go onto check compression. Is it extremely low?
Those are just some basic troubleshooting tricks that ANYONE who works on cars should know, even if they've never seen fuel injection in their life.
It's not rocket science, and if you used the time you spent complaining about how much you hate fuel injection to actually look up how it works, you'd probably stop hating it so much.
