Gearing options needed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

So, I'm really trying to decide how I want to gear my beast. Currently, it has a 4 speed, NP205 (I think), 4:10 rear (not orig), 4:56 front (orig). I am planning on going with a 4" lift and 35's.

So, I'm going to stick with the 4:10 ratio but I'm not sure about the tranny. I've thought about swapping in a NV4500, or another option may just add a GV Overdrive unit. It seems like the GV option would be easier, and would probably be about the same costs but I wanted to see if you all had an opinion.
