- Good for 4.25" stroke with 114"-117" engine looking for an agressive bolt in
- Produces a wide powerband
- Responds very well to increased bore and/or compression, exhaust system and air cleaner
- Use of performance valve springs is not required but may result in a quieter, smoother running valvetrain.
- Cam specs measured in the engine on the lifter @ 0.050 using a 1.61 rocker arm ratio.
- Feuling does not recommend tuning beyond stock emissions standards.
NOTE: Not for M8 with 121" VVT engine.
NOTE: Overlap: 38
