From what I understand, the basic specs for the 2002 LS6 (and the LS1 for that matter) did not change from 2001. In that case, actual displacement is 346 cu. in. (5.67 liters). I pulled that from a number of sources, including http://www.sallee-chevrolet.com/ChevySmallBlockV8s/LS6.html. Could have just been "operator error" on Eckler's part
I usually check multiple sources for info. Everyone makes a mistake now and then and I have found my share in the CAC secs. Off the top of my head I beleive Mag Red II is listed as a color on the 97 and 98. That would be a rare car. Love the site but no one is perfect.
