I have a 1984 Chevy Cavalier. It has a 4-speed manual transmission, code M19.
According to the data I can find (car has no tach to confirm), this has a 4.10 final drive ratio with a .81 4th gear ratio. With 24" tall tires, the calculators say that at 85MPH, the engine will be turning almost 4000RPM in 4th gear (top gear). (I thought it was interesting that I could shift into 4th at 25MPH without any complaint from the engine, but this short gearing explains why!)
Is this common for 1980s 4-cylinder vehicles? Given that, when they were designed, 55MPH was the fastest legal speed?
Does anyone know what the redline for the engine in this car is? It's a 2.0L "122" engine, code LQ5. I've been unable to find this info.
