96 mustang GT 4.6 2V with PI swap heads, cams and intake on a non pi short block.
I am looking at upgrading the stock throttle body plenum but I am undecided because there are several size. Don’t know which one would be better for my engine. There are 68, 70, 73, 75 78mm sizes. I don’t plan on upgrading the rest of the engine too much. Maybe just a cam swap and that’s it. Which size do you all recommend that would be the best bang for the buck?
