Even with the 12 valve cummins, you can't hit 350 HP by just "turning up the screws"
Turbine housing, injectors, fuel pin, pump adjustments, exhaust and a high-flow air filter will get the old cummins to around 300 HP. Diesel Power magazine "Project Rustbucket" for reference.
As far as the 7.3, the 10K (or 18K?) resistor mod for the IPR, FPR shim (as previously mentioned,) IDM resistor mod, and DIY air intake. These will make only slight improvements to power output. To really get increased power, you will need a tuner, or chip. If you get a tuner/chip, BUY GAUGES!!! since you will need to monitor EGT and prevent cooking your engine, especially when hauling heavy loads.
