I have a 225 slant six with two 2 barrel carbs on it. Wanting great gas millage. the 3 speed automatic tranny that's original.?? is rebuilt. but what would be the best way to get the overdrive done or substitute a different tranny with an overdrive to get the best millage? I have yet to scroll around in the old posts.
