Some Mustang 5.0s are great, but those I"ve seen run at Memphis International raceway aren't the greatest. I've run 5 thus far and beat them all. Here's a video of a 5.0 on a great weather night, with a tune and other bolt ons that couldn't break into the 12s. That night my basic bolt on Camaro was running 12.4s @ 111:
