Well I don't plan on going multiport or nitrous so this mani should work for me? I just need some help finding the adapter I need. I seen that the offy's have the same bolt pattern for their intakes. They have a couple with that bolt pattern (3 3/4"x3 7/8") that adapts to the holley pattern. Unfortunately they don't give specs/drawings for the orientation of the patterns. Anybody have any leads or maybe links to such info?
