I own a 71 Dart that I am about 2 weeks or from putting back together. I just got new paint. I am replacing the entire drive train, which is where my question comes from. The original gas tank has the 4 vent tubes coming out of it. I am not using the original 318 engine and I am going to replace it with a 360. Should I replace the tank with a tank that doesnt have the vent tubes coming out of it. Are there any advantages to one tank vs the other?
