[Tigers] Distributor Performance

[Ron Fraser]

Bob
	I agree the Pertronix has been very reliable.  I think I installed
mine about 1980.

Mechanical advance is for performance
Vacuum advance gives you economy on the highway

Ford has what I call 2 styles of distributor; early style has an oil port,
later style has a tri lobe center section.

The early style has wear points at the advance weights which can hang up the
advance curve.
The later style eliminated those wear points and has a smoother advance
curve.

My thoughts are that everyone should check their advance curve so they know
the distributor is advancing correctly.

I like more MPG so I'm sticking with the stock distributor with vacuum
advance.

Hi Mark and Ron, I use Pertronix in a couple of my stock cars and also have
the MSD box and distributor in my street tiger. I like both setups, both
have been really reliable and it's really nice not having to think about gap
and dwell. For my stock mk2 I was wondering about the merits of using
Pertronix in my dual point distributor with only mechanical advance vs.
using it in a stock distributor with vacuum/mechanical advance. I have a
vintage dual point in there now and am using points. I just caravaned to and
from the Historics from LA with another mk2 owner. He has the dual point
with Pertronix ll I think. We both have stock 289's and I got about 21 mpg
on the trip using points and my car drove great. I think I'll switch over to
Pertronix with my dual point and see what the difference is. thanks Bob J.
