I really haven't looked into the mileage, but with a BB you can't really expect much.
Free flowing duals would help, if it come equipped that way.
Cam change? Don't know what would be computer friendly.
My '86 does run with 235/85-16 tires, as far as I can tell it's been a tow mule most of its life. What I did find out is the stock replacement torque converter was rated for about 1300 stall (low). Truck hasn't been on the road enough to clock the mileage.
