I have an 86' K10 SWB and did the same thing as you. I lifted it 4" and installed 35x12.5x15's and regeared with 4.10's. My truck has the 700R4 originally too and can tell you go at least 4.56's. If you keep the th350 or go a turbo 400 then i'd go 4.10's. That is my only regret. When i get it on the freeway i feel like it is barely idling am I"m doing 60mph.
