I own a 99 vette that'll be supercharged with a Vortech system. I want to know if one or both of these cams are capable of passing smog/emissions test? They are both listed below. I would also like some input on these cams or any other cams I haven't mentions.

Both these cams are 'mild', so with a competent tune, both should be able to pass emissions, mind you, the comp cam would have an easier time.

If passing emissions is your primary concern, go with the Comp cam. If power is, then the Crane is your ticket.

Stock 02+ ZO6 cam is a very good cam for supercharging and will pass emission and make more power than you could really use on the street!

The 02+ zo6 cam is:

204/218 .551/.547 117

As you can see they are the same and make the same power. You can buy a used zo6 cam and save some dollars also.
