Hello I"m new here, and have been enjoying the forums for a long time.
I have a 1983 full size Ford Van. I has a 4.9 inline 6 have red forums on boosting power with offy intake and efi manifold. I need to know if anyone has tried it in a van with 4 barrel intake (offenhouser). Will it clear with 4 barrel carb on sides and top? Thank You very much.
