hope you can help

Sounds about right. Though that's mostly your rear-end gear. In 86, 2.77 was the most common rear-end gear. My 86 will do 80 at about 2000, but I always looked at the road and the rear-view mirror more then the tach at 120mph

 

It's not high geared. Third is direct drive (1:1) which is what most final gears are, and the overdrive is .70:1 which is on average, lower than most overdrive transmissions. And the 700R4's 1st gear is more agressive than most GM transmissions.

The 700R4 is, however, reknowned for it's incredibly wide 1-2 ratio gap.
