little story that might be relevant. today a black c5 vette, dont know exactly what year was riding my ass as i was coming up on my exit, he took the exit behind me rode my ass all the way down the exit and then when we got on the highway i just stayed in the slow lane figureing he would blast by, he didnt and he kept riding my ass. so i said **** it and dropped back down a gear, when he heard me, he pulled out into the other lane and tried to go by me, i droped the hammer and didnt let of until 120, he never was able to pass me until i let off. once i let off he got up next to me and was shacking his head giving me the thumbs up. I dont know how fast those vettes are a suppose to be, i think they were like 350 crank, it looked and sounded pretty stock. and i think it was an automatic.
What i know is that it was a damn good feeling to hold him off with a normally aspirated 4.6l that i created.
