    I installed a Viper (Dana) 4.10 gearset into my stock Dana 44 case with no grinding or other problems. It's a late 89-96 housing.

    I put 4.10 Dana gears in a 1990 ZR1 (replacing the 3.45 gears), but I didn't like it... 4.10 is too much for the street - it made me feel like 'Joe Hot Rod' and I drove that way. After a few months I put the original gears back in. After that experience, I think the 3.70- or 3.73 gears would be the best compromise on the street (if you're running a 6-speed manual)...

    Most guys I've read about on Corvetteforum.com say they love the change to 4.10s. Of course that all depends on what your transmission gearing is as not all transmissions have the same gear ratios, not even 6-speed manuals...not even all Tremec T56s. One reason I went with the 4.10s is to be able to better use the 0.5 OD sixth gear on the highway. And I think a 10.91 overall ratio in first is going to be great in town. It would be like a later Muncie M20 with a 4.26 rear gear or an M21/22 with 4.96 rear gears...nothing wrong with that. My Porsche has a 13.15 overall first gear ratio and it's a blast.

    I cannot imagine running less than 4.10 if 6th is .5-1 that makes final drive 2.05-1.
