At the Bay Area meet last week, one owner who is planning a 3.2 liter six conversion also talked about substituting a flipped HB (19:31) gear in fifth in place of the standard ZD (31:22) in order to lower engine revs at highway cruising speed and increase fuel economy. Does anyone have any experience with this transmission modification?
