comp XE HL 275 camshaft

It's the aggressive rates that makes these modern fast ramp cams idle smoother for a given duration at fifty. They don't bleed off cylinder pressure as much because the advertised duration is much less.

The VooDoo 268 is very close to the Comp XE268 about 4 degrees more at 0.050. Can't see it idling much differently than the Comp XE268. I have heard folks say the Comp has quite a lope to, must be my combo.

In either case I don't think you can go wrong with the Comp XE series or a Lunati VooDoo.
