Your dads old-school thinking is correct to some degree...but really only applies to carbed cars. Fuel injected cars are a different animal altogether, esp. modern ones. Our Bonnevilles LOVE 180* stats, esp. when they are in the south. But let'* get this back on topic, shall we?
Before you do ANY mods, you *should* do an "ultimate" tune-up. Changing you 'stat would be considered in this, so no harm there. BUT, you should ALSO do the following:
1) Ignition tune-up. Change plugs and wires. Also take your coils off the ICM and clean that gunk that is probably in there. Is this good for MORE horsepower? Not really. Is it good for REALIABLE horsepower? I think so.
2) Cooling system flush. A cooler engine is a happy engine.
3) Synthetic oil. Again don't expect much of a power gain. But it does help in running a cooler engine.
4) Throttle body cleaning. You would be grossed out if you actually saw what is in that body. You will have to take the TB off the car to do this.
5) Oxygen sensor. If it is old, it will be lazy in detecting the optimum air/fuel mixture. A new one will not only get you better mileage, but will also gain you a few horsepower to boot.
Now, see where I am going with this? Before any "mods" should be done, you need to ensure your engine can handle them. And, you can *easilly* discuss this with your dad and sell the above list as "preventative maintainance" items because..well, they are!
