nice kill man...I've also been hoping to run up on a newer ss myself just to see how I'd do. a stock one of course and preferably an auto so my chances go up lol.
Don't worry you will easily beat one, I also have a Mach 1 with 36k miles borla catback, drop in k&n, mgw orange short throw ad frpp aluminum shaft and I ran one it looked pretty nice black on black from around 20-120. He saw me then he pulled next to me so I said oh he wants to run so when he hit it I did as well but we were together and I thought to myself okay we'll this guy is playing with me anytime now he will pull away but no I started to pull on him by The time we finished I was ahead by 1 1/2 cars. I know he was trying because when we finished he pulled down his window gave me a thumbs up and said "good run". If I can beat one you should easily beat one considering you have more mods than me. I also don't know what his car had.
