I have been working with both a 440 Mopar and a 1988 FI 460 ford for many years on the Mopar and 2 years on the ford.
I think I have the Ford nailed so far as making it go goes.
I believe I could easily adapt the Ford FI using all junkyard parts to work on the 440 using stock 440 man, drilled for injectors' with the ford fi horn on top. That's about all the 460 man is.
The early Ford FI is very forgiving and will run without EGR or O2 sensors to get you going in a pinch.
The real question is would stock MPI FI be worth the effort.
The attractive part to me would be that using all used parts it would be far cheaper than a new Holley 750 and none of the carb issues.
Anyone done a conversion of this type that is workable?
