The steel version of Hamilton's 178/208 towing grind, for builds where a cast core is no longer the right choice. Duration is 178 degrees intake and 208 exhaust at .050 inch on a 110-degree lobe separation angle, with .310 inch and .320 inch lift. The profile favors low-end torque and turbo spool, pulling strongly to about 4,000 RPM.

Key Features

  • 178/208 duration at .050 inch, 110-degree lobe separation angle
  • .310 inch intake and .320 inch exhaust lift
  • Built for torque and quicker spool, with usable power to roughly 4,000 RPM
  • 49-state EPA compliant
  • Steel core requires cam tunnel bushings and steel tappets

Fitment

  • 1989-2007 Dodge Ram 5.9L Cummins
  • 2007.5-2018 Ram 6.7L Cummins
  • Flat-tappet engines only

Installation Requirements

  • Steel tappets are required
  • The block must be machined for cam bushings; running a steel cam directly in a cast iron tunnel will damage the block
  • Verify piston-to-valve clearance during assembly regardless of advertised drop-in compatibility
  • Hamilton Cams warranties camshafts only when installed with Hamilton Cams tappets and valve springs.

Break-In and Oil

Flat-tappet valvetrains require 15W-40 oil with adequate zinc, phosphorus and molybdenum (5W-40 in sub-zero conditions). Approved oils include Valvoline, Schaeffer's, Mobil Delvac Extreme, LIQUI MOLY Touring High Tech, Driven Racing Oil and Shell Rotella.
