camshaft · FF-0319

Does an ARDUN conversion need a different camshaft?

Yes, to work properly. Steve says many of the original bolt-on conversions probably kept the stock Ford cam, which is not optimized for the setup. Current conversions use a cam designed for these heads and valves, and he says that is the right thing to do.
