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 think this is what I had in 2000 F250. Was pulling 15k trailers on overdrive just fine. It was 4WD, so in case of need for low gear I could switch to LOW, but beside going into dirt, I don't recall need for it. RPM comparison is straight math. Ask your grandson ;)
