The challenger is for stoplight to stoplight fun. My wife takes her car and I take the Chevelle and we go cruising on the weekends. We throw the kids in the car and have fun. Every once in a while she will take it to the strip when we run the race car. I plan on putting the drag radials on the challenger and make them work. The chevelle runs mid 12s at 109mph. I was trying to figure out which KB Hyper piston to put in the 440 for the challenger.
