GT would lose hands down. Umm.. saleen and mosler would be hard... I'd probably take the mosler, but it'd be close. The mosler has a ls6 in it I believe and the saleen has a Fe. The weights are pretty similar, and the stances are both fairly low. I would have to say in a road race it'd depend on the driver, and in a drag race it'd depend on the gearing. It's almost too close imo.
