BBT installation support
Have the installer verify cam timing, piston-to-valve clearance, spring installed height, coil-bind and retainer-to-seal clearance on the actual engine. Confirm the lash or preload procedure for the supplied cam and follow its lubrication and run-in instructions. BBT can assist with part selection, installation and calibration.

Application and selection
Use this component only where Crow specifies this exact part number for the engine and camshaft combination. BBT has intentionally not assigned an unverified vehicle route to this product.
Installation checks
Degree the camshaft where applicable and verify piston-to-valve clearance, valve-spring suitability, retainer-to-seal clearance and the complete valvetrain geometry before final assembly. Set valve lash or hydraulic preload to the exact cam and lifter combination.
Ordering and BBT support
Built by Boost & Tune can help confirm the correct Crow camshaft, springs, retainers, locks, lifters, rockers, timing components and supporting hardware as one compatible package. For modified cylinder heads, non-standard valves or an unknown existing combination, provide the engine specification and measured valvetrain details before ordering.
