I went to a car show tonight with my buddy user name ( its slow ) . He has a 2002 ws6.M6, MS3 cam,4.56 gears, pacesetter LT's, LID, 3" exhaust, Vortec Supercharger kit. He also took out the carppet, and has spent somewhere close to $2,000 on all tubular suspension parts (whatever it's called ), I was riding in his car w/ a few other friends and all I have to say is WOW!! Car weighs under 3500 pounds with us riding in it. It would throw you back in it's seat like crazy. His numbers are 520whp/49x tq. I just want to say I was very impressed and it gave me a dream for my Z28. I wanted to know what he would run??? He IS on the stock rear end and has an additional 50 shot of nitrous to run. He isn't able to run at the track because he knows his rear end would blow. Assuming all of this, what would you think????
