RE: Dont worry about all Mustangs...
I make a great living with the Mustang crowd, and know that with a few mods you can pull better 60's then the challenger will ever dream of. Good thing the 1/4 mile is more then 60 foot
I think to compare you have to look at both N/A, or both at boost. Either way the challenger is a better starting point with the semi hemi math, and larger C.I. displacement.
