The XP cam works best with a blower, but I'm sure it can be used on a N/A motor as well. If you don't know much about the xp cam, it is made by comp cams. The specs are
- 212°/224° at .050"
- Intake Lift .325" (.520" lift at 1.6:1 rocker ratio)
- Exhaust Lift .335" (.536" lift at 1.6:1 rocker ratio)
- 116 Lobe Separation
