Watch if you have the 1850's or the like and the narrow perrimiter of the manifolds carb base flange.There are channels under the carbs base that are not seald off. The gasket is there but there is no manifold underneath to support the gasket and you end up with vacuum leaks. Guessford Machine filled parts of my carbs channels with JB weld(I think). My setup is hood clearence chalanged. So adding another plate and gasket is counter productive.
If I were doing this from scrarch and didn't have any induction, I'd go with a single four or EFI incorperated into a single four inake manifold , probably another tunnel wedge or a Victor open spider type.Not much available for dual fours.Nothing else is oem why should the carb be oem.They are making better stuff today.
