Hamilton Cams 6.7 Cummins Competition Block | 07-B-006 | 2007.5-2018 Dodge Cummins 6.7L

Want to make big power without the expense of buying longer rods, or a deck-plate block? This is the answer!

Features:

• 1? thicker deck
• OEM 6.7 deck height
• 1? thicker cylinder base
• the cylinder wall that is cooled is effectively 2? shorter due to the extra material at top and bottom of the cylinder
• Much Thicker main webbing
• OEM 250 MPA cast iron or improved 300 MPA high tensile alloy
• If running High tensile, alloy we suggest DLC coated Toolsteel Total Seal rings.
• High tensile alloys should be honed with diamond hone.
• Cam oiling from mains has been shrunk from 7mm to 5mm for improved bottom end strength
• Do not tap main holes deeper, this is the source of the failure for most of the block failures we see
• Due to the many requests we have for different bore sizes we left the bore as cast so it can be anything you want, from approximately 4.0? to 4.250?
• The thinner the wall, the less cylinder pressure you can run without failure
