Throttle body and injector sizing chart?
Is there a chart somewhere showing the stock throttle body sizes offered on the various Ford EFI engines?
I could also use a method for telling the size (LB/HR) of the injectors as well.
And another thing, they offer bigger throttle bodies for the 5.0 but the manifold hole is hardly any bigger than the throttle body, so how is there any increase of flow if the passage between the throttle body and the plenum is the same size?

FYI I'm adapting a non EFI engine to EFI that's a 220 cid V8 and plan on using ford EFI parts.
The ones with a throttle body listed are what I pulled from a wrecking yard so far and I got the complete upper manifold off an older 5.0 with a 50mm throttle body, and the 65mm throttle body and injectors off a 4.6L SOHC (Thunderbird), port EFI.
So do we assume if a 5.0 engine came with a 50mm body they get 14lb injectors?
So do we assume if all the 4.6L SOHC engines came with a 65mm body, and they get 19lb injectors?
Here is what I have found so far.
Here are the injector sizes for the most popular Ford performance and truck engines. These engines are the most popular for swapping into early musclecars, street rods, and trucks.
•5.0L passenger (302), port EFI: 14 lbs./hr.
•5.0L HO and truck (302), port EFI: 19 lbs./hr.
•4.6L SOHC (Mustang GT), port EFI: 19 lbs./hr.
•4.6L DOHC (Mustang Cobra), port EFI: 24 lbs./hr.
•5.7L truck (351W), port EFI: 19 lbs./hr.
•7.4L truck (460), port EFI: 28 lbs./hr.
Can someone let me know the throttle bodies that go with the different engines?
