Hi Dough!
I have a 427R too, with more or less the same experience, even with a dual plane intake.(RPM Performer)
Changed to a smaller carburator (Quick Fuel 750) modified timing curve, idle at 1.000-1.100rpm and now it is ok. Fore sure it is not a cruiser Motor but driveable above 1.400 and the fun Begins at 2.000.
