[Tigers] Distributor Performance

[wseay]

The objective of the dual-point distributor is to increase dwell to get a 
larger spark.  With the Pertronix you get the increased dwell with none of 
the disadvantages of the mechanical point set in the dual-point setup. 
There is one potential advantage to the dual-point distributor that you 
might want to consider though.  The dual-point distributor is set up to 
optimize performance.  As such, it has no vacuum advance and, presumably, 
has a mechanical advance curve which is intended for maximum performance 
rather than the best compromise between economy (i.e. with vacuum advance) 
and performance.  If you install a Pertronix unit you will retain the stock 
vacuum and mechanical advance which should provide the best 
economy/performance compromise.  If you want the combined advantage of low 
maintenance from the Pertronix and optimal performance from the dual-point 
you can install a Pertronix unit, disconnect the vacuum advance and diddle 
with the mechanical advance.

Is there any performance advantage of a Ford dual point distributor over a
Pertronix electronically  triggered distributor.  There certainly can't be
a maintenance advantage to a dual point, so is a dual point's firing worth
it?
