I have conducted further investigations into the intake manifold saga. The Edelbrock 4.6l Victor Jr EFI intake manifold would fit on my 4.6l SOHC engine. My newest problem is the size of the intake center, which is larger than the OEM size opening and would not take the normal plenum. While searching, I came across Edelbrock "Intake Elbows" (similar as plenum) which would seem to fit on the Victor Jr intake. My newest problem is that Edelbrock's intake elbows would seem to work for LS1, LS2 and 5.0L engines, but may not fit for the 4.6l.

Does anyone know if I could use and Edelbrock intake elbow on the 4.6l Victor Jr Intake manifold and take a 75mm normal throttle body?
