whats the quickest time possible for a stock 98-02 ss or z28 auto/standard

 

The fastest documented time I have seen has been an 12.8, drivin by Even Smith and it was in GM Hightech Perfomance. This is NOT an average time and don't be fooled into thing your car will do the same. On average they are low 13 cars.

 

Hot Rod Tested the 98 z28 in May of 98 and here are the performance test results:
bone stock of course. JD1969 Is totally right low 13's all day.
0-60: 5.2 seconds
Quarter Mile: 13.34@105.75 MPH

 

by the way JD do you have any engine bay shots of your car?
