Parts to install it: cam bolts to match your cam gear (1-bolt or 3-bolt); 7.400 in. pushrods (hardened; 7.400 in. is stock length, so measure first); timing cover gaskets (the front cover comes off to change the cam); timing chain (replace it on a high-mileage engine or with a big cam); valve springs (.660 in. lift) — stock springs aren't made for this cam.

Check current price at LSE9x.
- Tune: Aftermarket cams need idle, fuel, spark and torque-model changes.
