Mopar HEMI Gen 111 Big Bore Engine Block

Reduce the weight of your Late Model HEMI engine by almost 100lbs with the new aluminum HEMI Gen III cylinder blocks. Each block is 98lbs lighter than the cast iron HEMI Gen III version.

This one allows you to build a 440cubic inch HEMI. You heard it right. A humongous HEMI Gen III can now be built from this Mopar aluminum block.This aluminum block has rough-machined bores that can be taken all the way to 440 cubic inches. You don’t have to go that far. The steel liners can be bored as much or as little as you wish.
  • Semi-finished to 4.140”. Can be bored to 4.185”.
Features and Benefits:
  • Lightweight aluminum gives added performance in more ways than one – better acceleration, braking, vehicle dynamics, you name it. Lighter is better.
  • Water jackets have been completely re-designed to accommodate a Siamese bore. Extensive Computational Fluid Dynamics (CFD) studies have been performed to balance thermal conditions for consistent and reliable performance.
  • Crankcase clearance is designed for a 4.125” stroke crank shaft. A 4.250” stroke will fit with machining around the oil drain backs.
  • The main bearing supports as well as the bottom end of the block have been completely redesigned for the additional strength required for a forced induction 440+ cubic inch motor.
  • 8620HR billet steel main caps with four bolt center caps beef up the bottom end for severe performance applications.
  • Capable of supporting a dry-sump package for reduced windage and to allow more engine installation options, including lower vehicle center-of-gravity.
  • Camshaft bearing support area increased to permit the use of a 60mm roller bearing, if desired.
  • Lifter bores can be opened to 1.060” for a bushed style lifter.
  • Additional boss in the front timing area for an idler (double roller chain). Additional boss for a front gear drive, plus attachments for a front motor plate.
All HEMI Gen III dress items will fit Gen III aluminum blocks (front cover, oil pan, oil filter mounting, front end accessory drive, etc…).
