Rough-idling 360, can't figure it out!

I think the wear on the edge is normal, as in the lower edge of the 8 contact in the dist cap. have you pulled plugs to check the color see which one look fouled etc. If oyur fuel system checks out, do some googling/rsesearch on the pertonix. I think there is some ide issue complaints out there on the web. Of course the quick verify would be to throw a points distributor in and see what you got.
