What makes an ignition coil A Hei coil?
What makes an ignition coil A Hei coil?
Developing a better HEI coil was actually where Performance Distributors began in the ignition business many years ago. Davis says the key to maintaining consistent voltage throughout the RPM range is in the internal construction of the coil. “We build our coils to use heavy gauge windings and more windings per coil than the OEM parts,” Davis says.
How long does it take for a Hei coil to reach maximum resistance?
In a points system, it would take 10 milliseconds for the current to reach maximum with a coil that has 2.6 ohms of resistance. The primary windings of an HEI coil have only 0.5-ohm resistance, allowing maximum current to be reached in approximately 3.4 milliseconds.
What does a Ford ignition coil look like?
The coil looks like a black cylinder with a center wire similar to a spark plug wire and two side posts with nuts and wires attached. Remove the large wire from the center of the coil by pulling it straight out of the coil. Remove the retaining nuts and all the wires attached to the side terminals on the coil as well.
Is there an ignition coil upgrade on a muscle car?
One of the more popular ignition upgrades on both modern and classic muscle cars is the ignition coil.
Can a Ford distributor be used as a Hei module?
He eliminated the vacuum advance can and filled in the hole to make it appear more like a mid-’60s Ford dual point distributor. He has converted the wiring to a two-pin connector as used on an MSD distributor. We can now use this distributor to trigger an HEI module.

What’s the normal ohms reading on a Hei coil?
Disconnect the green and white wires from the module and touch the positive meter lead to the green wire and the negative lead to the white wire. The normal reading should be between 800 – 910 ohms. Testing the primary circuit of the coil.
How do you install a HEI distributor on a Oldsmobile?
1. Disconnect the Flame-Thrower wire harness from the distributor cap. Remove the cap from the distributor housing. 2. Install the distributor gasket over the gear, and up to the distributor collar. (gasket not required on Oldsmobile and Ford applications). A small amount of gasket adhesive will help to hold the gasket in place. 3.
