You could also use the Pantera Electronics ignition system.
A/C cutoff controlled and monitored by vacuum rather than rpm with many
other features built in..
Trickle charger, ignition retard during start, electric fuel pump control -
low rpm setting + cutoff if engine is no longer running, etc etc..

A A A Hey Rob
A A A A 6AL only limits the coil drive output.
A A A A 6AL-2 or a 6AL plus has a Retard Step output
A A A "Retard Step. This retard is activated when 12 volts are
applied and
A A A rpm is above the Step1 Rpm value."
A A A It's meant to keep those 14:1 motors from blowing the teeth
off the
A A A ring-gear,
A A A but just program it to go true at 4000 and do your thing
with a
A A relay.
