I heard this story from the Camaro owner so I suspect the spanking was quite worse than what he relayed. Basically he owns a 90's Camaro (I can't remember the exact year, 96 I think).
Basically he was on I-90 in Grant county where the road is straight and flat for miles. He was speeding along and according to him it was actually speeding. About 80 MPH. A Dodge Cummins deisel pulls along side him and matches his speed,. He looks over and hits the gas expecting to see the Dodge in his rear view mirror. He glanced over and the Dodge was right beside him. So he punches it up. Dodge never falls back so he gives it all he's got and they hit 125MPH.
According to the Camaro owner, the Dodge was right beside him for about a minute and then pulled away from him. He swore that Dodge had some non-standard mods on it.
