When you get a car that is a few years old some things on the car can be changed. That is definetly a 340 grill, they only put them in the cars that had 340s. But the question would be did they change the motor to a 318 or was a 340 grill put on this car. A lot of guys knew the little differences between the cars. If you were going to race on the street, you had to know your cars. There were also guys that put the lower performing body panels and markings on the top performing cars to throw another racer off as an easy kill. But after one run you knew you were had. I really like that car of yours and wish like you that I still had mine. But we will make some new memories with the new Challengers and have an awsome time doing it. Let the street wars begin.
