i have a 335 with drop in and airscoops and i raced a Charger SRT which is very similar numbers wise to a challenger SRT. lot more muscle than an RT and we were basically Dead Even. i had him off the light by 1/2 a car he had me by a nose through 3rd. I now have added a JB3 tune and im 100% sure i would walk an SRT challenger, charger, 300. Theyre way too heavy and dont have that flat torque curve like we do. You would embarrass a R/T dont even waste gas racing one.
