MustangForums.com - New Possible Car, feedback appreciated

Ok well i'm thinking about buying my 3rd Mustang, i've owned a 1990 GT, i own a 2003 GT at the moment, and i'm considering selling my 2003 GT to buy this 1988 GT and pay off some bills. All feedback is appreciated, i was hoping to squeeze a little bit more power outta this car so throw me some ideas. IF i buy this fox body, it will be my first carb car, so any common knowledge to know when owning a carb will also be greatly appreciated.

Here's the specs of the car
