Mopar 6.1L Hemi Aluminum Blocks

Product images may differ from actual product appearance.

Gen III Hemi Aluminum Blocks are 100 pounds lighter than 6.1L production cast iron blocks. Lightweight aluminum improves performance in more ways than one: acceleration, braking, weight distribution, and vehicle dynamics.

  • Compatible with all Gen III 6.1L Hemi engine parts
  • Gen III Hemi dress-up parts also fit Gen III Hemi aluminum blocks
  • Completely redesigned water jackets accommodate Siamese bore
  • Lifter bores can be opened to 1.060" for a bushed-style lifter
  • Camshaft bearing support area increased to permit a 60mm roller bearing
  • Billet steel main caps with 4-bolt center caps strengthen the bottom end for severe applications
  • Crankcase clearance for 4.125" stroke crank (4.250" will fit with machining around oil drainbacks)
  • Can support a dry sump package for reduced windage and to allow more engine installation options
  • Computational Fluid Dynamics (CFD) studies have been performed to balance thermal conditions for consistent, reliable performance
  • Main bearing supports and the block's bottom end have been modified with the strength required for a forced induction 440+ ci motor
  • Additional boss in the front timing chain area for an idler, additional boss for a front gear drive, and attachments for a front motor plate
