Has anyone had 355 gears with a 7.3 diesel was thinking about changing to them from 410's but want to know if it will be geared too low, also what rpm will 65mph, be at 410's at 1900 is about 56mph
I have the 7.3 with 355 gears and 5 speed stick shift. Been all over the USA hauling a 9.5 ft. camper with no problems. My previous truck had the 410 gearing and when I ordered the 7.3 I went with the 355 gearing for a quieter ride. Unless you are pulling a big 5er you don't need the 410.
