I am looking at a 1989 Corvette with the auto transmission. What kind of performance would one expect from this car with no after market modifications?? What was the horsepower rating for this year Corvette? Thanks!!

Shamster said:The Mass Air Sensed System was still being used for the '89 production year. The only physical difference between the Mass Air Sensed system and the Speed/Density system is whether a Mass Air Flow (MAF) sensor or a Manifold Absolute Pressure (MAP) sensor is installed.
