Duraspark

No new job yet but offered some freelance work helping compile an automotive directory. Not as fun as writing articles but good experience and a high heel in the door so to speak.


Girls went to Build A Bear with "J" and came home with new outfits for their bears then treated me to an extended fashion show. Very cute!


Dropped off my Rust Proofing article at World of Wheels magazine this week, will be my second published article under my new name.


Temperature was above freezing so took an hour to recurve the distributor on the Mark IV. The 76 Mark always felt that you had to push it through the air while my 72 Mark felt much more lively. In fact I would often find myself well over the limit when I troubled to glance at the speedo. Does that mean I am a fast girl HA HA!


After some prolonged research I found out that the Ford Duraspark electronic ignition has a reversible distributor cam, unfortunately mine only had a choice of 21 and 16 L slot meaning the car had a 32 degree centrifugal advance. Combined with the 8 degree initial advance the 460 V8 had 40 degrees of timing not including vacuum advance. So no wonder she pinged when ever I tried to advance initial timing.


Apparently the trick is to reduce centrifugal advance to 20 degrees and make initial 15 for a much peppier engine. I did my best to limit centrifugal advance by making as bushing to limit advance and then reset timing. A test drive didn't reveal any pinging and the Lincoln was much happier. All by eye ball and seat of the pants need to track down the correct distributor cam or buy a digital calliper to set exactly.
