1. 200hp, 300ftlbs torque
2. Dual throttle body won't work with a 5.0 type intake. No way the truck/van intake will fit under the hood, and unless you want to stay with the 200 hp number you want to ditch it anyway.
3. Use a '89 or newer Mustang computer. The Mustang setup is Mass-air, sequential fire system. The van computer is a speed density, bank-fire system.
4. You can swap intakes to a 5.0 style 351W intake. To fit under the hood, the options are very limited - GT-40, Trick Flow, and Spyder are about it.
5. The van setup is a bank-fire, speed density system. Not very efficient and will not respond well to modifications. So it may be 90% there, but you'll end up throwing most of it away anyway.
If I had to do it all over again, here's what I'd go with -
