cams?? I am confused

All of MoPars cams were called Purple cams because they came with purplr paint on them.
A cam that will not have a lumpy idle should have a 112 or 114 centerline. Most poerformance cams are on a 110 or a 108. Crane cams are good for this 112 centerline.

As far as 1 step of from stock, you'll find there really is no exact cam or measurement for that. Tell us about your car. What performance parts you have added to it and what tranny and rear gear ratio you have.
