IMO 4.56 is a minimum for the 33" and up rubber you are runnin.

My 4 speed 68 K20 burb is runnin 4.57's with 33" tall BFG's, and it drives very nice to me.

My 02 yota 4x4 with 31" tall tires with 4.56 gears, runs a bit high rev but it is a 5 speed so it's all good to me.

4.11 may squeek by as a DD that never see's the dirt or serious work, and is just a run around rig meant to just look like a 4x4.

Anything taller than 3.70's and you will be driving a dog of truck and get terribly MPG on top of that.
