I have a GM D106 370 7306 /10 bolt rear. 37-10 it is connected to a 350 turbo trans. Need to change to a highway gear. What year is this? what do I look for?

If you have a 10 bolt rear end with a 3:70 ratio the lowest you'll be able to go is 3:08 or maybe a 2:93 ratio without changing the diff case. If this car is not stock which it sounds like you can also put in an overdrive transmission which will more thatn likely do what you want.
