I run 3.73s in my BB 402 and 700R4 with 265/70R17 tires - 67 Chevy 4WD - 14 bolt. I would not change it but it does hunt between 3 and 4 at about 37-38 mph with light throttle like in a 35 mph zone- same with my other 2. Even with a small block I like the 3.73s behind a 700R4 - my 59 GMC 4WD (215/85R16)- 12 bolt, and my 42 Chevy 29 inch tires 10 bolt.

For 60 mph cruisin I like the 3.73s. But since you are making a switch 4.10s as kwmech says above may help the hunting problem.
