Best SB motor parts/specs

[cheyenne10]

I am looking for everyones suggestions for a build list for a good SB.

It will be going into 1/2 ton 4x4 pickup with T350/NP205 and 3.73 gears, currently 31" tires probably be going to 33s. I like to pull in and run Costco pump regular unleaded and get decent mileage. Prefer a strong durable motor. Had Goodwrench new motors and did not like them at all. I need more HP and torque for faster fun and pulling. Would like this truck to cruise over mountain passes without feeling like I am pushing it for all I have.

Assume 2 bolt main
using stock alt, PS and AC brackets
stock air cleaner setup
exhaust manifolds, no headers

Need recommendations and brands on

cam
carb and intake
heads
internals
etc.

Lets here your preferences
