Installation Notes
Professional engine builder installation required:
Remove old camshaft - Disassemble timing gear/chain and valvetrain components
Inspect cam bearings - Replace if worn or scored
Always replace lifters - New camshaft requires new lifters (tappets) for proper break-in
Lubricate properly - Apply high-quality camshaft break-in lubricant (assembly lube) to all lobes and journals
Check camshaft end play - Measure and adjust with shims if necessary
Time the engine correctly - Align timing marks per manufacturer specifications
Prime the oil system - Before first start, ensure oil pressure reaches the top end
Break-in procedure - After installation, run engine at 2,000-2,500 RPM for 20-30 minutes to properly seat lifters
