Those are good times for a stock LT1. I have a stock 97 SS M6 and my best time is 13.89 and 100.5mph. I do run at 1800 feet though. Mine is the only reasonably stock LT1 that has gone above 100 mph here that I have seen.

Well did you race with the cutout open? You shouldve ran it closed, more back pressure on that car and it shouldve ran better.

1997 SS M6 w/about 70k on the clock at the time.
