Hello all, I'm in the process of doing a 700R4 swap and I wanted to start documenting my en devours for the benefit of the community.

The truck is a 71 K10, 350 SBC with a TH350 and a NP205, pretty common. In swapping to the 700R4 I am looking for reduced highway RPMs, as a result of the lower highway RPMs reduced heat from the engine, and (I doubt it but will happen) but better gas mileage.

Stay tuned...
