Fuel injection on a 250 I6?

[ACS081783]

I've been doing some thinking and digging around on the internet for some information to put fuel injection into my I6. My goal is better gas mileage and more power/torque. I found that Clifford Research had an intake manifold that would allow a triple weber DCOE throttle body injection setup. Also found the "crazy torque" head but that's off topic and another project. My question is... if I were to do this triple weber sidedraft setup, what size injectors would I want to use? Has anyone tried this setup with any success? Any information would be appreciated.
