Exhaust is pretty much it. Anything else that will make a notable difference is going to require going inside. A high comp piston and maybe a nice cam would wake her up though. Or a 416 kit.

Best when doing a bunch of other upgrades. The stocker is capable of mixing plenty of air and fuel for just an exhaust. Changing to a larger carb might get more top end but usually at the cost of lower end power.
