I guess it’s personal preference. In my CSi with 4-speed and 3.25 the car felt fine but at 65-75 the car felt like I was running at higher than usual rpm, 5-speed with 3.25 felt a bit pokey and annoying at starts/stops, 5-speed with 3.45 feels like most other cars I drive - good acceleration and comfortable highway speeds. During the drive down from Seattle to Monterey it felt great on the highway but then we didn’t have trouble keeping up with some more modern cars in th various rallys through the backroads. But I will admit that I’m not a guy who tends to push my cars up into the 4.5-6 rpm range routinely while others love riding near redline.
