Give me the really big picture on manual trans options

[zac]

I’m starting what is probably a fairly long process on getting my ‘70 K10 suburban up to “really nice stockish driver” condition. Nothing more than that. Standard 465/205 with 350 and 3.08’s. I know you guys are more into offroad stuff, but the depth of knowledge on this board is amazing.

Want to use this truck in retirement for low key, long-range travel, we spend most of our time on backroads, but obviously you have to go on interstates sometimes. Overdrive would be great, but swapping to a 700R4 seems like a total cop out. I am aware of the NV4500 option. I’ve also seen the a833 option, etc. My thinking right now is just build the best low-end torque 350 I can and then rebuild the stock 465/205 and call it good. The 465 is a pain on the road, but it’s time-tested and I’ve been driving them since the 70s. Modifications, fabrication and expense don’t bother me, but it needs to be worth it.

Thanks in advance!
