Depends on DA, track prep and driver skill as everyone else said, I'd say probably high 8's to 9.0's with a 81-82 mph trap speed. If you go to Atco NJ on a cool day then you will be a lot better than that if you are high in the Rocky Mountains you will be a lot worse than that.
However with a few minor bolt on's you can drop that significantly. My last trip to the track yielded a bunch of 8.3 and 8.4's at 84.5 to 85.5 mph.
I'm in west Tennessee, altitude about 450'. I know that launch procedure, track prep and temps can affect ET (I've been racing for about 35 years). Just wondering what others with pure stock autos have experienced. Thanks
