Drop-In Cam Fitment Requirements:

• 12v Engines:
  • Piston protrusion: ≤ 0.025"
  • Valve face depth: ≥ 0.055" with a standard head gasket
  • Intake centerline: 99°
• 1998–2002 24v Engines:
  • Piston protrusion: ≤ 0.025"
  • Valve face depth: ≥ 0.038" with a standard gasket
• 2003-2018 Engines:
  • Piston protrusion: 0.018"
  • Valve face depth: ≥ 0.038" with a standard gasket
• Clearance Adjustments:
  • If piston-to-valve clearance is insufficient, use an oversized head gasket or cut valve reliefs.
  • Check clearances even for drop-in cams (use our clearance calculator to simplify the process).
• Steel Cam Version:
  • Requires at least two bushings in the cam tunnel to prevent wear on the cast iron block.
• New lifters are always recommended when changing a cam.

Break-In Instructions:

• Preparation:
  • Apply a liberal amount of quality assembly lube to the cam.
  • Do not start the engine without oil pressure.
  • For new engines, apply assembly lube to the oil pump and prime the oil filter.
• Oil Change:
  • Change the oil after the break-in procedure.
  • Pre-primed filters and oil systems help the engine build oil pressure faster.
• Priming Procedure:
  • Disconnect the fuel system.
  • Spin the engine with the starter until oil pressure is visible or oil flows from the rocker arms (limit starter use to 10 seconds at a time).
• Initial Start:
  • Once oil pressure is verified, start the engine and run at 1200–1500 RPM for five minutes, then shut it down.
  • Adjust the valves after the initial run to ensure proper settings.
• Additional Tips:
  • If re-torquing or “hot-torquing” the head, do so before adjusting the valves, as this affects valve lash settings.
  • Enjoy the improved airflow after break-in!
