Stock for stock, drivers race. Equal drivers 5.0 FTW. Physics. Get over it.
It is still possible to like and enjoy your slower SS. And if you regularly beat stock 5.0s with your stock SS, respect. You can drive. If you ran into my friend with his pure stock 5.0 GT auto you would lose. 12.4@114 uncorrected. The real ET on a good DA night. He spent 100+ runs perfecting his launch coming down from starting at 13.1. And he can drive, he will tree you if you are sleepy. That being said most coyote stock autos I see at Atco are running right around 13.1+- depending on the DA. 6Ms are all over the map.

Autos FTW.
