Help me with A833 Gear ratio choice wide or close!

Yellow Rose, I agree that their isn't a gear set to maximize the use of the 3.09. the 1-2 syncros have a tough job anyway. I have an aluminum 3.09 box that was in my 64 polara w/ a 440 and it worked ok but I changed it out because it just wasn't for me I guess 4:10 Dana.
