My Service Manager here just got an '04 GTO and his first words were do you think your 335 will outrun it?
I just had to smile and remind him that the last '04 I ran at the track here couldn't break into the 13's and I ran 13.8s, plus the LS1 f-bodies I have walked on the road (stock for stock).
Both are great cars but I think the GTO is a little more unforgiving on the launch.
