I believe they both have the common ratios of 3.27, 3.55, and 3.73, the 9" being used for F250/F350, the 8" for F150. more info than that is above my paygrade.

The F-250 and F 350 would be full floaters with 8 lugs. There were some F250s with semi-float but still 8 lug. These 3/4 amd 1 tons would typically have a dana 60, or in later years a sterling 10 1/4. The 4:11 is absolutely perfect for the island with so many hills and really 60 is more comfortable on the rare freeway trips. My rear tires are a bit over 30" tall so there's a little 'rubber overdrive' as well. Most of the 8 and 8.8 seem to be set up for the springs being under the axle, and mine are above. I have moved and welded spring pads before but the '57-'72 seem the best fit. I'm glad I have received a favorable response on this subject and thanks for the input. And I do kinda like a bit of 'overkill' sometimes. I will continue my research!
