To start, make sure the hood is grounded with a strap.  Try using the one dangling off your firewall that you mentioned in a separate thread.  And, check the antenna lead connections to the radio and antenna.  If you have a mast antenna, make sure the base is anchored to a clean ground.

It's difficult to know just how much you don't know until you know it.
In other words... if people learn by making mistakes, by now I should know just about everything!!!

Sargent, is the interference a "whiirrrrrrr" or "zzzZZZZZzz" sound that changes with RPM?  A 'whir' is often associated with alternator operation, while a 'zzz' is generally ignition noise.  Follow this link for useful information: Electrical Noise Prevention.
