Default Is there a difference in performance from the 90 to the 91 model?

I know there are slight differences in the front fascia but how about performance?

Some people say that some of the 90s cam timing out of the factory were a little more aggressive than the other years.....I know the car got a little heavier as the years went on....

When they tested the 91 in the 1/4 mile it ran a disappointing 13.8 I believe...They attributed this to hot engine temps and maybe a slipping clutch..

Top end speed I believe was still high...

Just curious....

Stock for Stock I doubt there is any noticeable difference in handling or speed.

Reds ha??????
You're confused, bless your poor little heart...
Everyone knows that in the quarter reds are good for
about a second and 5 mph better than any other color!
Don't believe me?
Start a poll...
