390 Fuel Injection
Has anyone ever considered taking a aluminum intake and milling it as a base plate to mate to a 351/302 fuelie intake, and converting to fuel injection. I imagined lining up intake runners, pushrod locations, etc, would pose big headaches, but,............. If it could be done, it might be willing to give it a shot.
Sealing might be a problem, and how to bolt the damn thing together?
Hmmmmmmmmmm?
I need to stop giving serious consideration to the things I think up after a 6 pack.
Anyone see any other potential headaches?

I think it would be a huge PITA. If you want fuel injection, which DOES have great benefits both for power and mileage, look at a holley system. You can program it all yourself, and the installation is fairly straightforward. I just put one on my 360. It's nice to just be able to turn the key and go.
For the cost of adapting it, and the cost of reprogramming it, I really think you'd be ahead to get the holley system, be it the TBI or the port fuel injection.

I'll look into it. Kinda like the idea of keeping it all Ford, though, if you know what I mean. Was thinking of raiding the salvage yard and using the mass air conversion kit from Ford Racing. EBay occasionally has intakes.

If I were to fuel inject my 360/390 (which I hope to do one day), I would go with a GM system with the stock 2bbl intake. Not very glamorous but I think this would be the easiest and cheapest way to go, using easily available junkyard and off the shelf parts.
I know of a guy on the internet that sells kits based on the GM TBI parts for $900 complete, I dont know if I am allowed to link to his site though from here.

I think the hardest part would be to line up the intake runners, followed by the issue of valve cover fitment, fuel rails, oxygen sensor, etc. Beyond that, if I use the mass air conversion, what's to stop this from working ---
By the way, this is just idle speculation; I'm not planning to multilate good engine parts anytime soon.
Maybe someone could convince Edlebrock to fab up a lower intake to receive a stock EFI intake, fuel rails, ................

I think its very possible but be sure you know everything you are getting into... Here are some other issues to factor in...
Correctly sized injectors (flow rate), plumbing a return line, upgrading the factory charging system to accomodate the greater electrical demand, external fuel pumps and selector switches if using dual tanks, cam and crank signals in a format that the factory computer can utilize, etc.
It would probably be simpler to consider an aftermarket system. While a factory system answers a lot of component compatability questions, adjusting its preset fuel delivery tables to match the flow rate requirements of the engine can be very complicated. Mass air helps to a degree, but it does fine adjustments to the gross settings already programed into the computer. Aftermarket systems like ACCEL, HOLLEY, FAST, MoTec, Edelbrock, etc. are designed to have these tables modified which makes setup much more manageable.
Just food for thought.
