Degree up or down of tailshaft will depend on how the suspension sits and how the engine is mounted. The goal is to get the carb mounting flange level when the truck is parked unloaded. If you have EFI then you have more flexibility, especially port injection.

You also want to consider the U-joint angle when setting up the engine. Optimum U-joint angle is 2-4 degrees. Maximum generally recommended by driveline manufacturers is 7 degrees.

It helps me to make drawings during this stage.
