The car in my avatar. Original Cuda 440 4pd super trak-pak. Stock it ran 13.0 @ 104 mph. Did some work to it and it could just touch the 11's but dialed in at 12.00 since I didn't want to put a bar in the car.
I ran the same plugs I drove back and forth to work with. I would just make a coupld high speed runs on the street to clean them out.
That car was terrible in the snow.
