K30 gear ratio

I am building a 86 K30. Seem to have a lot of housings front and rear with 4.56 gears. I was hoping for 4.10s. I am putting a 454HO crate engine in it with a 4L80E with a divorced NP205 or a Divorced Rockwell 221 T Case. What do you all think about running the 4.56 gears in this truck? Not an off road rig for sure. 235/85/16 tires on it. I am thinking about highway rpms.
