Re: TR Upgrade
Ford didn't make a 304, but I get the point. (I'm a typo slinging fool! I feel your pain![img]images/icons/blush.gif[/img])
You have done the leg work by changing the cap, rotor and plug wires.
Now your ignition will support higher spark energies.
The E-core coil is only a little boost in voltage, but voltage isn't everything.
The E-core design give you a longer discharge at the plug gap.
(meaning that the spark duration lasts longer and gives your plug more opportunity to get the cylinder lit.)
You will be pleasantly surprised with what you have done now, and you can always do the coil later when it needs replaced...
An Extra $45 for a premium coil and $15 for the connector is a big bite and can wait until later when you feel more comfortable with the upgrade and have some extra spending cash...
