    I believe the cam is soft so you need a softer dist gear. Most companies can now make roller cams that will accpt a standard steel dist gear, I had one like this in my last motor. BTW - mine was a Crane brand cam. /forums/images/graemlins/thumb.gif

    Roller cams are machined from SAE 8620 billet steel and the gear on the cam isn't compatible with a cast iron distributor gear.

    The downside is that bronze does not have the stength of iron, so it wears at a higher rate.

    I would hope most of the newer aftermarket pieces for the street are all this way now, but as was mentioned, most companies now use a pressed on gear that is different material (I would hope same as dist.) so you don't have to worry about it.
