13.4 is a great time for a N/A contour. I would like to see that without nos though. You would have to have some good horsepower to the ground to get that time with the weight of that car. I manage low 13's in a 2300 lb car, with 265+ hp at the wheels, and posi trac. There was a guy in the probe club I was in who pulled off a 13.1. I think he had a built J-spec motor with a 75 shot of nos though. It was nice to see a probe beat a mustang 5.0, z28 and a few other older muscle cars.
