Dodge Magnum "Throttle Boss 114"218/223 Hydraulic Roller 5.2L/5.9L

🛠️ Installation Instructions

REDLINE CAMS – Dodge Mopar 318/360 Magnum Hydraulic Roller Camshaft (1992–2003)

⚠️ Important Notes Before Installation

• Magnum engines use pedestal-mounted rockers; check pushrod length with aftermarket cams.

• Requires high-zinc (ZDDP) oil during break-in and regular operation.

• Verify valve spring pressure, retainer-to-seal clearance, and piston-to-valve clearance.

• Recommended upgrades for most performance cams:

  • Performance valve springs & retainers

  • Upgraded timing chain set

  • Headers & free-flowing exhaust

  • 2000+ stall converter (for aggressive cams)

  • Reprogrammed ECU/tuning for max gains

🔧 Tools & Supplies Needed

• Basic hand tools (sockets, wrenches, screwdrivers)

• Harmonic balancer puller

• Torque wrench

• Assembly lube (moly-based)

• Break-in oil with ZDDP

• Mopar Magnum intake, valve cover, and timing cover gaskets

• Engine timing light

📖 Step 1 – Disassembly

• Disconnect the battery.

• Drain coolant and remove radiator (recommended for clearance).

• Remove accessory drive belt, fan, water pump, and timing cover.

• Remove distributor (note rotor position).

• Remove intake manifold, valve covers, rocker arms, and pushrods.

• Remove lifters and store them in order (if reusing).

• Remove old timing set and camshaft carefully.

📖 Step 2 – Camshaft Installation

• Clean block and inspect cam bearings.

• Coat new camshaft lobes and journals with assembly lube.

• Carefully slide camshaft into block (avoid nicking bearings).

• Install new timing chain set, aligned to factory timing marks.

  • Optionally, degree the camshaft for max accuracy.

• Reinstall timing cover with new gasket and harmonic balancer.

📖 Step 3 – Valvetrain Setup

• Install lifters with assembly lube in their bores.

• Reinstall pushrods and rocker arms.

• Torque rocker pedestal bolts to factory spec (17–19 ft-lbs).

• Check hydraulic preload (Magnums use non-adjustable rockers):

  • If preload is incorrect, correct with pushrod length.

• Verify valve spring pressure meets camshaft requirements.

📖 Step 4 – Reassembly

• Reinstall intake manifold with new gaskets.

• Reinstall distributor, setting base timing near stock.

• Reinstall valve covers, accessories, radiator, and coolant hoses.

• Reconnect wiring and battery.

📖 Step 5 – Initial Startup & Break-In

• Fill engine with break-in oil (with ZDDP).

• Prime oil system (via oil pump driveshaft with drill).

• Start engine and bring RPM to 2,000–2,500 for 20–25 minutes.

  • Monitor oil pressure, coolant temp, and listen for abnormal valvetrain noise.

📖 Step 6 – Post-Install Checks

• Change oil and filter after break-in.

• Recheck ignition timing with timing light.

• Verify pushrod preload and valvetrain stability.

• For EFI trucks: allow PCM to relearn or have it tuned for best performance.
