The all new released LTR block from concept performance has taken the Gen V LT industry by storm! The block strength comes from the way that its cast and the heavy duty sleeves. The block is a HIP casting allowing it to be the densest form of cast aluminum possible. We are glad to be using this block for many of our builds now! The LT world has not been given an affordable six bolt option for blocks, UNTIL NOW! We offer the LTR in a 400" and 427" short block,  depending on the crankshaft you choose. We also offer these LTR shortblocks in a 1400+ HP package and 1800+HP Package. We have many Gen V LT options and are excited to add the LTR as one of LME's many package options.

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 a 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 the 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
