Just came in the mail today from MaxBore. I'll get it measured up later for a finish diameter. Bore finish and throttle plate fitment look pretty darn good.
There is a taper from the factory on our TB's. There is a reason for it.I am confused. I know that you must know that the smallest diameter in the throttlebody will dictate the max flow possible. So larger outlet vs inlet doesn't do any good. The inlet side is the restriction.
