Drill Template for LS Truck/SUV Iron Blocks

Do you have an LS Truck block and need the second mounting hole for low mount alternators or other accessories? We've made it simple with this easy to use template. Just attach the template with your factory hardware, mark the hole, then drill the hole with an "R" drill bit (.339", or 11/32"), then use an M10-1.5 Tap. (This is in a non critical part of the engine block.)

  • Mark the center point for precise drilling & tapping.
  • Made in Wichita, Kansas from aerospace grade, USA produced billet aluminum
  • Includes: 1 drill template only
