I believe this was on the 275 drag radial too.
Don't forget to take the driver of the car into consideration also not just the simple combo of the car, Melissa is a great drag racer with a lot of track experience. I believe i read that she had ran her 11 second GN for a few years at the tracks before the performance of the power plant was increased to the level that she could run the car into the 9 second range at 138 mph.
