6.1L Aluminum Blocks
- Gen III Hemi 6.1L Aluminum Block
- Finished Bore: 4.055"
- 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
