1989-2018 Cummins 230/240 55mm Competition Camshaft (07-C-230/240/55)

Hamilton Cams designed this cam to outperform roller cams for all out 2.6″ and 3.0″ pullers and high RPM drag trucks. This was obtained by starting with a 1mm larger core so that they could keep the base circle large enough to keep the nose angles from being too sharp. The less sharp nose with the wider lobes allow the cam to live under extreme spring pressure at high RPM. You will need 180-200# of seat pressure and 460# on the nose. Ideal for engines operating in the range of 3,800-6,500 RPM with excellent flowing heads.

  Is this cam steel or cast, and what lifters would go with it ?
