All other things being equal, which of course they never are, what ultimately transmits power to the road (and HOW) are the tires. Everyone agree with that? Hope so...
Weight-to-Power:
ZL1 = 7.10 lb/hp (?); 305/35-20 = 23.0" total tread (as per GY)
Z06 = 6.33 lb/hp; 325/30-19 = 23.1" total tread (Optional 335/25-30s = 25.0")
ZR1 = 5.26 lb/hp; 335/25-20 = 25.0" total tread
Forget Manufacturer, and weight distribution, and tread patterns, and UTQG for a moment...
GT500 = 5.77 lb/hp; 285/35-20 = 21.3" total tread (10.8 + 10.5, as per GY)
Under-tired? Let's compare it to its closest Weight-to-Power competitor, shall we?
2010 Viper non-ACR = 5.76; 345/30-19 = 26.4" total tread NO ELECTRONICS!
Draw your own conclusions...
Now, I'm gonna push back the Barcalounger, put my feet up, grab a tasty beverage, listen to some Paul Hardcastle (I recommend "Serene"), and wait for something "encouraging" from Dearborn/'Ring/VIR/Milan...

a more telling way to look at it:
The GT500 makes 631 ft-lb of torque, has a first gear ratio of 2.66 and a 3.31 final drive ratio. so about "5,555" ft-lb of torque makes it to the wheels.
The ZL1 makes 556 ft-lb, same 2.66 first gear and a 3.73 final drive ratio. so 5,516 ft-lb makes it to the wheels.
So the camaro has 40 less torque to the wheels and has more tire to deal with it. the GT500 will have more "trouble" getting off the line in comparison to the camaro but once it is moving the smaller contact patch offers less resistance and lends the GT500 an advantage from a roll.
So yes, given the stock tires the camaro will be easier to launch if the GT500 and ZL1 had the same suspension,wheels, weight, but different tire widths.
just looking at lb/hp is about as telling of performance as looking at the color of the car.
