Are spark plug wires all the same?
On the surface, spark plug wires are a pretty basic part they carry spark energy from the distributor (or coil) to the spark plugs. But when you actually go to purchase a set, you find out that there are a million different kinds with many different features.
What are the wires on a HEI distributor?
If so equipped, connect the electric tach wire (20 gauge brown) to the "TACH" terminal. The three wire connector from the HEI distributor plugs into the three wire inner receptacle on the HEI cap marked C-, GRND, and B+ (it's keyed to only go on one way.)
What are the different types of spark plug wires?
Spark plug wires come in three basic types:Distributed Resistance wire. ... Inductance (mag) wire This type has a spiral wound core of copper/nickel alloy wire. ... Fixed Resistor wire This type of wire has a steel or copper metallic core with a fixed resistor in the plug boot to control RFI.More items...
Can you mix and match spark plug wires?
What is even more imperative than matching cable length is that you do not mix up the order of the spark plug wires. Improper installation of these wires can result in poor combustion or misfiring of the cylinder, which will cause drivability issues and potentially severe damage to the engine.
Are most spark plug wires universal?
Spark plug wires are commonly direct-fit to work on a specific application. This makes installation very easy; however, you can also find universal spark plug wires that can be cut to fit.
How do you wire up a HEI distributor?

Does HEI distributor need ballast resistor?
When using HEI, the distributor requires a 12 volt feed. In order to achieve this the ballast resistor or the resistance wire must be removed from the circuit and replaced with a pure 12 gauge feed wire.
How do you wire a GM HEI?

Should I use OEM spark plug wires?
Generally you will want to stick to an OEM-type spark plug wire, unless you're confident a high-performance product won't affect your vehicle negatively. Another key important factor is to always purchase new spark plug wires, as you'll never know how used second-hand parts are.
What's better 7mm or 8mm spark plug wires?
A more robust core provides a lower resistance path for the power, thereby allowing more power to reach the spark plugs. Additionally, the 8mm wires have a thicker outer coating that keeps the core safe from damage. These wires also have a thicker layer of suppression material.
Do performance spark plug wires add horsepower?
The short answer is Yes, when you replace the spark plugs and wires can increase your vehicle's performance. New spark plugs help keep your engine at its peak performance and efficiency levels.
What is HEI distributor?
The HEI distributor is still an inductive-discharge ignition, but exchanges points for an electronic device called a module. Since this system produces more voltage and amperage output than a point-type ignition, it requires a larger-diameter cap to prevent voltage crossfire inside the distributor cap.
Why are Hei coils cooler?
HEI Coils also run cooler because they are encapsulated in thermal epoxy, which dissipates heat more efficiently than oil-filled coils. The solid epoxy, in comparison to oil-filled coils also eliminates the possibility of leaks.
What is the benefit of a wider plug gap?
The benefit of wider plug gaps is a more complete burning of the fuel mixture. Myth 2: Internal coils (in-the-cap) are prone to overheat. This is probably the oldest HEI myth of all. Actually, an HEI draws only 2- to 3-amps, compared to the approximate 6-amps an external oil-filled coil draws.
Is a HEI rotor phased?
Myth 9: An HEI rotor must be phased. On an HEI, if you use the holes in the housing that were originally there for the vacuum advance, to install your vacuum advance eliminator, there is no cause for rotor phasing. It will already be phased correctly due to the original design. Myth 10: Not necessarily a myth but a fact.
Is RCI billet aluminum?
Almost all those generic unbranded distributors are "imported" by a company named RCI or RCM, or something along those lines. They are NOT billet, although they look it, they're cast aluminum that's milled down and mirror shined.
Can you run 8mm wire with HEI?
It's not mandatory to run 8mm wires with HEI, they didn't come from the factory that way. You can't run solid core wires either b/c the noise will interfere with the electronics. Personally, I like a good heli coil wire from MSD or Taylor, had good luck with both.
