2.73 vs 3.73
 

Lets say there are 2 stock mustangs with 5 speeds andeqaul drivers, 1 has 3.73 and the other 2.73. How many car lengths will the 3.73 beat the 2.73? From a stop and a roll?

Lower gears dont always make you faster I ran quicker with my 2.73's than with my 3.73's

From a roll the cars should run pretty much the same. A slight advantage to the 3.73 car. From a dead stop, assuming you were able to use the traction, the 3.73 car will beat the 2.73 car all else being equal by a a couple three tenths in the quarter.
