Re: Cam retarding?
There is no happy medium. Every setup is different. How milled your head and block are will effect it. Exactly how your exact set of cams are ground will effect it. The backpressure in your exhaust housing will effect it. Most of these cam companies are not perfect at setting up their cams. Some might have some advance/retard built into them on purpose or on accident. If you do play with your intake cam gear, it will also change your ignition timing.
