Now I want to know, also. The girl driving was a cute little blonde and she was all over that thing off the line. It was definately an MTX because she was shifting it like she meant it. I was parked next to her in my Mustang and there is something wrong with the carburator so I was revving it up to to see if the power valve was shot or if the floats were sticking and I think she thought I wanted to race. BTW, if anyone tells you Holly makes the best carbs, kick them in the head and buy and Edlebrock. It'll save you time and money.
