I would start with the basics before spending heaps of $ on it.
New spark plugs (go one heat range colder than recommended - higher number on the plug = colder, so if the book says BP5FS, then use 6's )
Check the distributor vacuum and mechanical advance - if the dizzy is points, fit new ones, but its probably electronic anyway.
If you have a spare $50, throw a new coil on it too.
set the base timing, on gas you could try around 14 degrees initial.
If it is still sluggish, then you might have other issues also, depending how old it is, look at the timing chain, or blocked muffler etc etc.
