Back to the basics...

Hard to tell just by looking what something runs...you can get a pretty good idea, but its tough. Take this picture for example...any guesses on what these mopars run?

Going from left to right in the back, 1/8 mile times on a typical summer day:

Red Duster (340): 7.6x
Sublime Dart (360): 7.0x
Red 69 Barracuda (440): 6.9x
Red 64 (I think?) Plymouth (real Hemi car): 7.2x
Green Dart (stroked BB): 6.7x
Demon (440): 6.8x

And my car up in front on a typical day (stroked 360), 6.7x
