LME Standard Shortblock Blueprinting Process:

  • Block is fully deburred & inspected for flaws
  • Cylinders diamond honed with torque plates for optimal clearance per application
  • Crankshaft journals indexed & trued to exact tolerance
  • Optimal cylinder geometry achieved with diamond hone and surface finish verified with profilometer
  • Chamfered oil holes for improved oiling to bearings
  • Cylinders machined for rod clearance per application
  • Crankshaft journals polished to 2 Ra or better surface finish
  • Block and components meticulously deburred & cleaned after machining process
  • Crankshaft balanced within ¼ oz-in tolerance
  • All five main bearings & all eight rod bearing clearances measured and adjusted for application
  • Connecting rod housing bores checked & adjusted for optimal roundness & size
  • Ring are precision file fit per application
  • Piston pin bores measured & adjusted for application
  • Cam bearings installed and test cam fitted to ensure smooth rotation
  • Block aline honed and set to low of spec for maximun bearing crush
  • All oil galley plugs and dowel pins installed
  • Deck surfaces machined perpendicular to mains & deck height set for optimal quench
  • Meticulous final assembly of shortblock
  • Cylinders bored (when applicable) on 4 axis CNC perpendicular to mains giving you a true 90o  V8
  • All tolerances, clearances, machining specs, and part numbers are recorded and documented in build sheet
