Petronix - was Re: <VV> Gargle on the overrun

[Duane, Jim]

Pertronix and hotter coil here as well.  Points are at .45, never
misses, boost in 2nd gear.

Additionally, you can run a hotter coil with the Pertronix.

And along with correcting the unsteady dwell of a worn distributor, the
P-II even varies the dwell a bit according to the rpm, making the
improvements even better.

If your points ignition is in perfect condition, moving to a P-I is
likely not going to make a noticable difference, while moving to a P-II
likely will.
