305 is the cubic inch size of your engine, not your horsepower.
The base model firebirds are either V6 MPFI or V8 TBI. Only the Formulas, Trans Ams, and GTAs have 305 or 350 TPI.

I just bought an '89 GTA convertible with TPI, so yours might have it. Look for something that says "Tuned Port Injection" right smack in the middle of your engine, on top, and let me know if it's there.
