I need the (2) outer carbs (4790 and 4789). These are obsolete. Holley makes a 4365 and 4672 that are similar in mounting and CFM. Wondering if anyone has experience with these carbs? I called Holley Tech but they really weren't that helpful. Will I need to do anything to get these to a similar tune?
