was he modded? If it was a 6 Id think you wouldve blown him away more than just inching him out.... Maybe he was just trying to save face over the fact that he just lost to a wagon...haha. Did they even offer Z28's w/ 6's in em? If it was an older stock LT1 i think a cobb stage 1 would be a pretty even match for it..down lower at least. if you went up to 4th you probably cut it off before you hit 100, which is where an lt1 would start to come alive.
meh..either way, like you said, a kills a kill, good job
