I was online today glancing at the engine specs for all the cars in the Factory Shootout and noticed the 08-12 Mustangs have newer/smaller pulley specs than previously listed. If I'm remembering correctly, the 08 and 12 used 76MM while the 10 used 72MM. Suddenly those pulleys are listed as smaller. Whats going on?
