Thanks for the replys,

I bought the manifold and doghouse without any of the other pieces. The doghouse had it's tag missing, and someone had pollished it, reducing it's value to where it became a very good suspect for a conversion. I've got a 5.3 Vortec throttle body and have mocked up in wood an adapter that will hang it where the original airmeter was. With an OEM ECU, My plan A is to thread the injectors so I can screw them into the manifold. A good friend came up with an idea how to use individual lines rather than a fuel rail. His idea will require some delicate machining and fabricating on the fuel line and connection. The rest is just standard injection wiring and plumbing.

I asked for your opinion because I'm concerned about being stranded somewhere with an ECU failure, and not having the ability to walk into a dealer and getting "next day" service. The reliability of the Ford, or other, is far superior to some of the aftermarket systems.

Plan B: If I settle on using a fully adjustable ECU, I'll mock up a fuel meter using large flow throttle body units installed into a fuel distribution block. This will allow for lines and nozzles like the original had. I don't see that having back pressure on the throttle body will actually create any problem in the mechanics of the injector, and perhaps the adjustability available in the aftermarket ECU will allow me to overcome a few shortcomings that I see. If it doesn't work, back to plan A.
