New GTOs have the Ls2, btw.. an easy way to know what a GTO has is just remember what a Corvette has because a GTO is a Pontiac version of the Corvette with crappier suspension.
BTW the GTO would lose mainly because of the weight that it has over the skittle..
If you guys want to see something crazy, goto streetfire and look for a video that has a Charger going against a SRT4 and the SRT4 puts buslengths on the Charger..
