I want to pick up a '00 - '02 Ls1 M6 (pref an SS or Ws6 in Black or silver

) im making the switch over from Ford. After seeing my friend run a 13.16 @ 107 in his '00 Z28 M6 with catback and lid it made up my mind. You cant argue with results! My current GT is an auto and now with full exhaust, my best last year was 13.68@101 and this year i was searching for 13.5's after the long tube headers. I was thinking about supercharging the GT but, im now pretty sure i want to make the Ls1 switch, just to mix things up a little bit. I will always have my 1969 R code 428 Mach 1, and after getting an F body i will have the best of both worlds.
