A points or Duraspark distributor is the weak link once a small block Ford starts making real power, because the trigger signal wanders as rpm climbs. This Pro-Billet unit uses a maintenance-free magnetic pickup and a precision reluctor for a stable signal, and it pairs with a separate 6, 7 or 8 Series ignition control that does the coil switching.

• Fits Ford 289 and 302 engines.
• Must be used with a 6, 7 or 8 Series ignition control.
