Re: [AMC-List] Electronic Ignition Changeover

[<francis.swygert@xxxxxxxxxxxxxxxxxx>]

Jeff, the Mallory Unilite I'm familiar with is a complete distributor.
The early ones had some problems, but that should be taken care of in
the current versions. 

If you want to retain a stock look the best bet is a Pertronix Ignitor.
It installs in place of your points, and you can keep a set of points in
your glove box just in case the Ignitor fails (which is rare). You have
to run a switched power wire to the Ignitor, that's the only give-away
that something has been changed, and that's hard to notice.

The next best for a stock look is the AMC model Ford Duraspark. It will
look like a later model, of course. As someone mentioned, it was used
from around 1978-91 on all AMCs, including Jeep Grand Wagoneers. 

You can go one step further and apply the TFI upgrade to the original
Duraspark distributor. Rather than redesign the whole distributor when
going to a high energy system like GM did, Ford continued using the same
distributor body with an adapter for a larger diameter cap. TFI stands
for "Thick Film Ignition" and is equivalent in performance to the GM
HEI. As noted it uses a separate coil. To get the full benefits you need
the special TFI coil as well as the plug wires and cap. The wires are a
necessity when using the cap due to the connector, but it will work with
a standard coil (but not much point). These parts can be purchased from
any auto parts store -- ask for the cap, wires, and coil from a 1984 or
so Ford F-250 w/460. It's best to search for "TFI Upgrade" -- part
numbers are listed on some sites.
