WTF build thread...

I am looking at a brand new Jericho 4 speed dog box.
I have always built engines, set up rear differentials and even built a few turbo 350’s and turbo 400’s but manual transmission gears and turbo applications are new to me.
I know turbos like a load and higher gears but actual internal transmission gears are “Greek” to me.

with a 3.55 rear end, how would these gears perform in my application? From my limited knowledge, it seems 1st is too low. Also, would 1:1 be a good final drive?

Any input will be greatly appreciated and thank you in advance.
