If it already has an AFB intake I would keep it, would make the FiTech swap easy. I wouldn't swap to an AFB intake though. The spread-bore intake design is obviously more thought-out when you comparing them side to side. The thing that surprises me is how the tri-power intake even worked as well as the 4 barrel intakes, each runner is a different length depending on if the 1st and 3rd carbs open up or not.
If I ever have to get into the engine, I will grind away the spread-bore holes on my intake so I can mount the FiTech directly to it. Being a practical person though I'm not about to tear into the engine to do just that. I will reserve the right to change my mind on that one though!
