Parts to install it: cam bolts (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. More: LS cam swap guide.
- Tune: Aftermarket cams need idle, fuel, spark and torque-model changes.
- Cam gear: Three bolt

From real tunes on similar cams
We don't have enough tunes on this exact cam yet, so this is what tunes on similar cams run at idle (within 6° intake duration at .050 and 2° LSA of this one; as of 2026-10-15). Idle settings follow the cam closely; WOT fuel and spark depend on the rest of the build, so they aren't shown here. Gen III and Gen IV computers use different idle tables, so they are listed separately.
28 naturally aspirated tunes on similar cams, Gen III computers (0411/P01, P59)
engines: 4.8 L, 5.3 L, 5.7 L, 6.0 L; computers: P01, P59, PCM (1997-98).
| Setting | Range | Median | Tunes |
|---|---|---|---|
| Hot idle target | 700 rpm to 900 rpm | 800 rpm | 28 (middle 80%) |
| Warm idle airflow, in gear | 8.0 g/s to 16.1 g/s | 10.9 g/s | 28 (middle 80%) |
| Idle spark (around 800 rpm) | 18° to 28° | 22° | 28 (middle 80%) |
9 naturally aspirated tunes on similar cams, Gen IV computers (E38, E67, E40)
engines: 5.3 L, 5.7 L, 6.0 L, 6.2 L; computers: E38, E40, E67.
| Setting | Range | Median | Tunes |
|---|---|---|---|
| Hot idle target | 600 rpm to 850 rpm | 750 rpm | 9 |
| Warm idle airflow, in gear | 6.6 g/s to 14.0 g/s | 8.5 g/s | 9 |
| Idle spark (around 800 rpm) | 13° to 23° | 18° | 9 |
What these tunes run, not your numbers: heads, injectors, converter, fuel and altitude all change what your engine wants. For starting values built for your engine, injectors and fuel, use the turn-on tune builder. A turn-on tune only gets it running: always finish on a dyno, and read our safe tuning limits before any wide-open pass.
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.
