If I was to run quad throttle body efi, would 50mm throttle bodies be too big?

To have a total area equal to an 80mm tb, you would need 40mm tb's. If you used 50mm you would have 1.5 times the area, so I would say that is too big.

(Edit: although you would need to allow a bit more area than a plain comparison would indicate for the 4 small tb's)

I would think they would be ideal.
Have you seen Bob Romano's EB?

He doesn't have the photo of the EB on his site any more that I can find.
I was bloody sure I took a pic but can't find it.
Not sure of the size of the throttle bodies on it were, but thought it may interest you.
Will keep looking for a pic..

I think Bob Romanos fairmont was in one of the early perf ford mags.It is similar to the one 347 has in the other thread.If it is made by DC&O it could be the same.

Bobs car has the 40mm setup, spins it to 7200 and made 440 rwhp.
