Stock 360 4bbl intake

That’s probably what I’ll do. The intake might just stay on for the turbo so the more flow I can have without moving the rpm range too high would be my goal.
If you are running a square bore, I'd make the center divider "skinnier" to better match the square bore carb. I don't know i'd go down much with it. You'll be doing that somewhat anyways when you raise the carb a little with an adapter/2 gaskets.
