On early FE engines the pulley WAS the dampener, the later ones (maybe about '68) used a separate pulley /dampener set up. I would guess the 390 is a later model or someone has put the later harmonic balancer on it. You can swap it out if you need to use aftermarket pulleys or get an aftermarket balancer.
