"stock Mustang"?
 

ok, i have 2 questions. with the "basic" mods below"
my 90 Stang(hatch) with the "basic" mods below, what can i run?
2. if i were to take out the whole interior? this would be on street tires. just curious too see what you guys think.

Might be able to rip off some LOW 14's in this cold weather.

My friend with the almost exact setup went 13.56 @ 97 on slicks. The only differance in your setup and my friends is that he had the stock headers. He had full interior and all power accesories.

there is a significant difference between slicks and stock tires though.
