Then go cheap...
Put 5.0L Mustang EFI on it and get a chip burned.
The distributor comes from a 1988 EFI 460; or you can take any other year 460 distributor and easily put 5.0L guts inside it by drilling/tapping a few holes.
Weld a couple of oxygen sensor bungs to the exhaust somewhere right after the 4-to-1 junction.
Use the Ford Motorsport "hot rod" harness intended for the 5.0L mustang, and get the sensor kit.
Get any of these Mustang boxes. A9L, A9P, A9S, A9T, A3M, A3M1, C3W, C3W1, X3Z.
Use a 90mm diameter mass air meter from a 2001 Lightning truck, get a filter adapter for the face of it so you can run a cone filter. Get the pigtail for the MAF harness as well; you'll need it...the connector is different than the ford stuff.
Use 42lb/hr injectors from the same application...1999 lightning truck.
Have a chip made for the 460 firing order, the lightning maf, and the 42's a long with your engine displacement. If you want me to do this for you, that's what I do.
For the intake, use any conversion manifold you want but make sure it uses a Ford throttle body and has provisions for a Ford TPS sensor and a Ford Idle-Air control solenoid.
Put it all together, and drive it.
This is well within the realm of factory EFI giving you the ability to service the thing at your local parts store and/or ford dealer. 42lb/hr injectors can do 450+rwhp and 500+ft-lbs at the tires without a problem. So will the mass-air meter I recommended.
For a fuel pump, use the external Bosch Porche Turbo pump. I can look up a part number if you need it. For lines, you can get away with -6, but I'd run a -8 feed and a -6 return to give yourself some headroom. Remember, EFI runs at 40psi; you don't need the big line diameter like a low pressure carb setup.
That's what I'd do, especially for a driver application like this. No need to spend big dollars on all the fancy aftermarket EFI stuff. If you can do a little fabrication yourself, or can weld aluminum and build/adapt your own intake manifold, you can do the whole thing for probably around a grand using boneyard parts and a little creativity. For the power you're talking about you could even use the stock 460 EFI lower manifold and build a simple box upper that adapts to a ford throttle body...that'd save you a bunch of money and effort.
