Need Info 1979 k10 Th350/NP203 to SM465/NP205 swap

[TheBlueBomber]

Hi everybody, I'm trying to swap over my 350/TH350/NP203 set up eventually to a ???/SM465/NP205. Motor wise I'm thinking 454 but for now leaving it a 350.

So I've got a question or two. I recently bought a '79 k10 with a 350/Th350/NP203 setup. The truck has been converted to manual locking hubs with the 203. I want to make it into a SM465 backed by a NP205. What year transmission do I want to look at getting? I think in 86 the tranny switched to a hydraulic clutch? Do I want the hydraulic clutch setup? How hard is the pedal assembly to set up? Any information/pics or build threads will be appreciated. Thanks in advance.
