mines a stock 5.7 6 speed and 3.73s. I got it in Nov just after my local track closed so I havent run it yet but it hangs with some friends cars that are in the low to mid 13s. The wheel hop with the stick shift is crazy and the clutch is so light compared to any classic musclecar, you really need to learn how to feather the clutch or youre gonna burn through some tires real quick.
Track opens next month so I will post some times, for better or for worse
The local Challenger guys all seem to be in the mid 13s with stock 5.7 cars though
