On the G92 option ...
"The Trans Am's 305-cubic inch, 5.0 liter engine ... does move the car reasonably well if its equipped with one of the performance rear-axle ratios; 3.27:1 or 3.42:1. Performance shoppers take note. In comparison testing of two identical fuel-injected Trans Ams, the one equipped with a 3.27:1 gear was more than a half a second quicker in quarter-mile and 0 to 60 times than a typical dealer spec car with a 2.77:1 rear-axle ratio. Unless you're keying up for a run at the Bonneville salt flats, you'll probably be sorry later if you skip the performance-axle ratio."
