I have a 1972 K10 with 3.73s, 32 inch tires, TH350, and a 396. It’s pretty good all-around but if I had to open up the axles for some reason I would swap in a little steeper gear like 4.11.

It’s hard for me to see how a 350 would do any better than my 396, so my guess is you’d want more gear than 3.73?
