These are the asbolute largest Blower / Nitrous cams that will fit without valve reliefs. They do require either our modified Intake Valves or aftermarket Stainless Steel Intake Valves.

Good Cams for an Eaton Swap, KB 1.7 or 2.1L, Vortech V1 or Procharger P1SC with 10 - 12lbs of Boost. Nitrous applications up to 150 HP. Will still work great with Stock PI Intake.
