It's probably just a single retard unit. But why would a vacuum
retard reduce performance? When I stomp on the gas, there's very
little vacuum left, and the advance on the distributer would be
advancing with engine rpm. I'm tring to think how a vacuum retard
would hurt performance. I guess from a dead stop it wouldn't be so
great, but hey, just advance the entire distributor! Anyone got any
insight on this?
