Hi guys and gals, I'm new here on posting, but have been enjoying your site
for awhile now. I finally got myself a 92 FC International w/ a Ward 14
window. It has a dt466 and a MT643r trans. The air ride axle is a 4:44 on
295x75-22.5 tires. I drove it 900 miles to get her home at 60 mph.
It may have run a little faster but I didn't like pushing her over 2250 rpm. And THAT
may have been pushing too hard, I'm not sure.
Anyhow, I been doing some figuring? My idea is to replace the 4:44 w/
a rebuilt ratio of 3:42. This will give me a 65 mph cruise speed of 1886 rpm.
Has anyone tried a ratio this fast? And IF I ever find myself needing to
REALLY GET SOMEWHERE FAST, I can go 70 mph at 2031 RPM. Though
most of my driving will be at 60 mph which is 1741 rpm. I'm thinking that
dt466 at 210 hp shouldn't have any trouble working this axle ratio. Your
