Re: '89 ported plenum
I don't have a pic of the throat area. I can get one if it's necessary though.
I have no idea what it was ported to, and I don't have a way of measuring it.

Re: '89 ported plenum
Did you notice any difference in performance with the porting? How much do you want including shipping?
