I have a Zf5 manual from a 460 big block in my 97 F350 with the 7.3 diesel. I have 4.10 ring and pinion gears and I went to 35" tires, so even with the 7.3 running out of RPM with the 35's I get a decent highway gear (like 2200 rpm at 65 mph)

The nice thing about a 5 speed manual behind a diesel is you can shift when you want to....

I WISH I had more OD...for long runs (Like from Colorado to Idaho) I am sitting at 3000 rpm for hours at a time...something the 7.3 does not mind, but it would be nice to have a gear splitter or aftermarket overdrive so I could do 75-80 mph and get my rpm down to like 1800...but that's a big chunk of $$$$
