I have the same problem you have!!!

I have eliminated all belt driven items, locked out my mechanical and vaccum advance, and STILL I have a cyclic metallic rattle at a steady cruise at around 2300rpm...It only occurs at that particular RPM and at an absolute no load situation...If you accelerate or decelerate ANY amount whatsoever the noise will simply go away...BTW, I actually advanced my timing enough to get the engine to ping just so I would know what it sounded like...And that ain't it!!!

Oh yeah, the reason I posted is because I am running an electric fuel pump, so I don't think it is the fuel pump eccentric causing the problem...I'm thinking valvetrain noise now but don't know for sure...
