I know the bullitts came with the tremec 3650, however when I went to the tremec website, it showed 8 different versions of the 3650. Four versions had a 5th gear ratio of .68, three versions had 5th gear ratios of .62, and one version at .74. Just wondering if anybody knows which ratio the 2001 Bullitts have for 5th gear. Here's the site:
