Greetings,
We have 54 F-100 that is in need of a power plant transplant. We are considering a 5.0 EFI engine but have no idea of what a stand alone ECM would cost or what brand to pursue.
Any feedback would be appreciated.

You can use a 1989-1992 Ford EEC IV module, A9P for AOD or A9L for 5-speed, and an aftermarket harness from Painless or American Autowire or Ron Francis Wiring. Hard to beat this approach for low-cost and it will give you SEFI-MA system with up to 25% adaptive fuel control to cover any power improvements you might want.
