It rides very nice at 70 mph with the 4.10s. I didn’t bother with a transmission swap for the blazer I restored later. It had its original th350 and that was a strong incentive to keep it. That said, I doubt I’d have swapped in a 700r4.
We have some 700R's in 2 wheel drives and they work great for carbureted old school rigs. The K10 I am building is all original, and I intend to keep the four speed. I have a new Gear Vendors OD that I am contemplating putting in it. That way if for some reason somebody wanted to put it back, no harm.

The ability to speak several languages is an asset, but the ability to keep your mouth shut in any language is priceless.
