The most popular package I've done here is the tko with a .64 and 3.73's.

I've done them with 3.50-ish gears as well. In Fact our daily had 3.55's with a .64 for a few years and it was fine, used it all the time at 35 mph.

I've since put the original 3.73's back in the Z so I could use the 3.55's in another project and quite honestly I can't tell much difference in overdrive. Darn thing got 22 mpg on the last trip with the big fat 780 Holley on it cruising at 75 mph lol.
