Instead of reinventing the wheel, why not swap over the fuel injection
from an EFI 302? You have three choices (and sub choices within those):
two injector throttle body (CFI) from an 84 or earlier car, port
injection from an 85+ car, or port injection from an 85+ truck. The
port injection intakes are vastly different car vs truck. The truck
intake had more height to work with. I think it is also tuned for low
rpm torque (while the car intake is for high rpm HP). I see plenty of
all three in the wrecking yards around here.
For your embedded controller project, make a scan tool. (Yes, about a
decade after GM, Ford added scan tool data output to their ECMs.)
If you do decide to put stock EFI on your '75, I can give you lots of
suggestions because I'm EFI-ing a '73 F250.
