Mine is .480 lift 274 duration, cam was grind by Schneider.Idling is very good at 800-850 RPM,as for performing i really like it,but it doesn't pull really hard as if i had .460lift 270duration,this will really make you feel power,on the other hand idling is not as good as with mine.You can feel the difference between original cam and the one i had, but it's more on higher RPM range.Depends what you are looking for if you want smooth idling i would go with what i have,if you are looking for more power,go with the other one.I think mine is better for everyday drive.
