Let's not start the blown 4.6 vs. LS1 argument again....horsepower is horsepower...doesn't matter how it's made. You show up in a LS1 F-body and get spanked by a new Cobra then call foul because of the supercharger you'll get laughed right off the track....same for the person with a N/A GT or Cobra then whines about the CID difference.

Now back to the actual topic. My F-150 Ext. Cab pulled a best 15.63 e.t. to date. Got a slip of a 15.77 in my Gallery though.
