It takes horsepower to go fast, and you are most likely adding horsepower with the 350. However if you have to turn 4000 RPM to make 70 with the 283 you will still need to turn 4000 RPM with the 350 to make 70.
Both the stock 4-speed and the TH350 have a 1:1 ratio in the top gear.
Your 5.14 rear is usually called an Eaton rather than a 10-bolt. I haven't counted the bolts holding the cover in place, but the size of the ring gear has much more significance than the bolts holding the cover.
Many GM rears the ring gear diameter is relative to the number of bolts in the cover, but even then the difference varies.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
