That's obviously not the case...
So by your account:

12.58 run in a 3.31 means that a Camaro SS will run a 12.78 given the same conditions?

Lets be realistic...it is not apples to apples.

Camaro has taller tires (along with more inertial mass), wider spaced transmission ratios, and a disadvantaged rear gear ratio.

Mustang:
1st 3.66
2nd 2.43
3rd 1.69
4th 1.32
5th 1.00
6th 0.65
Final drive 3.31:1

Camaro:
First: 3.01
Second: 2.07
Third: 1.43
Fourth:
1.00
Fifth: 0.84
Sixth: 0.57
Final Drive: 3.45

Do the math and the Camaro needs a 4.10 to balance it out (not factoring in the taller wheel which would bump it to a 4.30). This is far more important than the <200 lbs. weight difference any way you swing it.
