  • 6.0 L L76 V8 (361 hp)
  • 6.2 L LS3 V8 (415 hp)
  • NOTE: The Super Duty Blower Hub option is a thicker hub that provides greater resistance to hub cracking under high power supercharged applications (750 rwhp and greater). This option includes a new custom made timing cover seal to adapt the oversized hub to a stock timing cover.

  • NOTE: The Underdrive Alternator option is a larger diameter alternator pulley (2.800″) that is designed to slow the alternator down when ran on high rpm race engines (7500 rpm or higher). The underdrive alternator pulley will slow the alternator down and may cause charging issues at idle for street driven vehicles.
