* Bore and Stroke: 4.00 inches bore x 3.00 inches stroke
* Horsepower: Typically ranged from 170 to 190 hp (net horsepower, SAE standard varies slightly year to year). Advertised horsepower figures often varied depending on the application and manufacturer claims.
* Torque: Around 250-280 lb-ft

Important Note: These are *general* specs. To get the *exact* specs for a particular 1989 vehicle with a 305 TBI, you'd need to consult the owner's manual or a reliable automotive database like a Chilton's or Haynes repair manual for that specific year and model of vehicle. The horsepower rating in particular varied significantly based on the application and even minor differences in emission control systems between models.
