I recently purchased a 1988 GT and it seems to have a lack of power above 3000rpm and an idle problem when first fired up after acouple of minutes it goes away. The engine is a 302 bored .030 over with GT-40 heads (or so the guy says) cobra upper and lower intake, cobra maf and 75mm throttlebody and a F303 cam it also has a nice set of equal length shorty headers and flowmasters. It has been converted from speed density and is running 19lb injectors. Any suggestions? thanks
That setup sounds pretty similar to mine, except I don't have the MAF, cam, or overbore.

However, I can say that my setup has no problem revving to 6000RPM on the stock 19lb injectors and fuel pump.

Does it only have trouble at the higher RPMs under load, or does it also have problems in neutral?

If it only had trouble under load, then I'd say that inadequete fuel pressure is a possibility.

If it has trouble revving in neutral too, then I would think of things like worn valvesprings (especially with that cam), and the ignition system.
