Mark VIII vs 96-98 cobra conv


So im driving through Mexico this afternoon and a red cobra convertible comes cruising up next to me. We play a little till traffic clears, as soon as it opens up we both punch it at 65 With him starting 2 cars in front Im expecting to get walked and at first I hung till about 80 then I started pulling him in. By 110 we were even and shut down. He gave a thumbs up and laughed then went on his way. Is this right for my mods. He had a louder exhaust than me so I know he was on it.
