GTSTANG, why if you own a mustang would you give so many good comments about an LS1?
BTW an 03 Cobra SVT will beat an LS1 F-body. Even the Mach 1 gets close. The Mach 1 can do high 12's simply by adding drag radials. So you think practically the same engine supercharged is going to do mid 13's? Where did you get that time anyway?
