Application and fitment
Applicable BBT GM LS / engine-family routes shown for this product. Confirm the exact engine code and build before ordering. Supplier part number: 871293K
Supplied contents
- One Crow Cams 871293 hydraulic roller camshaft with the profile specified above.
- One VTKLS8 dual valve spring kit containing 4438-16 dual valve springs (set of 16), 10708-16 retainers, 10701-16 valve locks and VSV900VTEX-16 top-hat valve stem seals.
The VTKLS8 package is supplier-listed for hot-street LS applications and supports up to .650 in valve lift. Confirm installed height, spring pressure, coil-bind, retainer-to-seal clearance and actual valvetrain geometry before assembly.
Installation and configuration
- Confirm the camshaft part number, engine generation, camshaft drive, trigger arrangement and cylinder-head compatibility before installation.
- Degree the camshaft where required and measure piston-to-valve, valve-to-valve, spring coil-bind and retainer-to-seal clearances on the actual engine.
- Check lifter type, hydraulic preload or mechanical lash, rocker geometry, pushrod length where applicable and the required spring/retainer package.
- An active-AFM/DOD engine requires the correct mechanical conversion before a non-AFM camshaft is fitted; update the ECU calibration as required.
