Re: Rear end ratio for 700R4?
I'm thinking you need lower gears, especially if you have an early 700R4.
From experience, my 85 K10, with 3.42 gears had a hard time staying in OD below about 70.
A shift kit and TV valve made a world of difference, but was still kind of sluggish. On 2 lane roads I would hold it in 3rd, would shift in OD on interstate.
The 88 and later had the auxillary valve bodies, from what I understand, they were much better.
