Short list:
exhaust, head work, intake, cam, windage tray, blower(turbo or super charge), different carb, electric water pump, electric fan, ......could go on for a while. The things you want to do are increase the ability for the engine to breath and reduce the drag on the engine coused by the accessories. you could just add gears to the rear to make it feel like you have more power.
68 fastback, 390 4V premium fuel
80 5.0 hatch, just finished
91 5.0 coupe, daily driver
84 RamCharger 4x4 extreme mudsliger and winter junker

just to add to the above... they now make some underdrive pulleys for your stang that should give you 10-15 more ponies

·There are quite a few things.
How much money you got?
Hey, check out my website. I have a 66 Coupe that had the 289 2V in it. I ran 3 dyno runs between modifications trying to get more HP. It will give you some ideas.

Some more additions
If you don't go with a blower then add high compression pistons. The higher the compression the bigger the bang. You must keep increasing octane as you increase compression. So you can probably get away with 10.5:1 or 11:1 with pump premium (depending on cam) past that you need to add octane booster, seems i also remember people using water injectors as a cheap way to increase octane.
Fuel injection may get you more power than a carb. Electronic ignition if your still running points. If your running an automatic get a stall torque converter so that the power slamms into the transmission when the engine is into its power curve.
