A cast performance grind for street, towing, drag and stock-class pulling use. Duration is 188 degrees intake and 220 exhaust at .050 inch, giving a 1,700-4,500 RPM powerband.

  • 1,700-4,500 RPM operating range
  • 40-60 HP gain with supporting modifications

  • Works on both 12-valve and 24-valve engines

Fitment

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

Clearance Requirements

  • 12-valve drop-in: maximum .018 inch piston protrusion, minimum .055 inch valve face depth, standard thickness head gasket, 99-degree intake centerline
  • 24-valve drop-in: maximum .018 inch piston protrusion, minimum .038 inch valve face depth, standard thickness head gasket
  • If minimum clearance is not met, use an oversized head gasket or machine valve reliefs

  • Hamilton Cams warranties camshafts only when installed with Hamilton Cams tappets and valve springs.

Break-In and Oil

Apply quality assembly lube to all lobes and lifter faces, prime the oil pump and filter, then crank with fuel disabled until oil pressure is confirmed. Never allow the engine to start without oil pressure. Bring it fully to operating temperature, perform any hot retorque before setting valve lash, then change oil and filter before normal service.

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.
