EFI 4.9

Has anyone done a swap from fuel injection to carburetor? I'm wondering about the port configuration on the EFI head. Do I have to swap to an older style head in order to use a carbureted intake manifold? I've just never seen the two sitting side by side. Mine is a 1990 F150 with the 4.9 inline 6, 5 speed and four-wheel drive.

Yes. Multiple threads. Use the search function on here and start reading

I wouldn’t want to go backwards and remove fuel injection but it’s your truck so do what you want to it.
