OK not such a big kill. Lil red GTO with a 5.7. Young kid with a rather plain looking early 2000 ish GTO automatic. He jumped on me going down a four lane and well it was not close on a 45 MPH roll. Nice looking car but kinda plain. Even let him get a car on me on another go around. It got ugly quick for him. He got beside me and we had a converse. So I believe an early GTO 5.7 automatic with little to no mods is not going to be a challenge for an R/T. Oh and we never broke the speed limit ;)
