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.

Tuning checklist
  • Tune: Aftermarket cams need idle, fuel, spark and torque-model changes.
  • Converter (automatics): 3600+ rpm converter required
  • Clearance: Check piston-to-valve clearance (especially with milled heads)

Installing it? Follow our LS cam swap guide (Gen III and Gen IV, any chassis), with every torque spec you need. In a 1998–2002 Camaro or Firebird, the F-body cam and valve spring swap goes bolt by bolt.
