coil mount for the edelbrock heads

[wrench87]

i purchased the msd blaster 3 coil with the high tower the directions state it must be run straight up and down it is not epoxy sealed like the blaster 2.
i was wondering if any one makes a mount that would go on the edelbrock head?. i know fms has a mount with one hole .

wrench87 You are getting NERVOUS, Any way If the car is not going to be 100% correct, mount the coil on the inner fender. Having cool air blow on them is better than raditor air. Coils make enough heat of there own. Heat, vibration, and low voltage are the main killers of coils. It seam that when they die it's in the middle of no where and not an auto store in sight. This effects oil filled coils more that epoxy "E" core ones. Mounting it vertial is the best way. Next question------ Rick L.

rick, i have my efi coil mounted to the side panel, i want to mount it to the head for 2 reasons a nice short coil wire then the wiring from the msd box could run with the distributor harnes?. i havent decided where to mount every thing yet so it is still up in the air.

[Barry_R]

Keep the coil wiring away from the distributor magnetic trigger wiring.

[RICK LAKE]

wrench 87 What Barry says with running MSD wires and coil wires together, DON'T do it. I run shielded cover on the 2 wires coming from the distributor to the MSD box. They run under my single plane intake manifold, along with my EFI harnesses. Rick L.

I have Eldabrock heads an my coil is mounted vertical on them they have holes to mount it.

[Rick Parker]

This is an example of an OEM designed bracket (available from many Ford & Mustang suppliers too). It allows the coil to be bolted to the front of either Cylinder head.

so where are people mounting there coils on a carbed fe?, could you run the msd wires down the passenger side of the intake and the coil wires down the drivers side with the coil mounted to the drivers side cyl head?.

[RICK LAKE]

wrench87 Either place works. vertical with an oil filled coil is not a good idea. I have and seen them explode on cars and leaves a nice little fires, my jeeps and car 3 times. All coils where Accells, 2 oil filled round ones and 1 super coil. You can run the wires down the same side but have 1 set of them in a silver conduit to help remove outside EM signals to the MSD box. I have the twisted ones in the conduit tube. No signal problem with the same setup for 10 years. Grounds and power are the most important things for MSD systems. 2-3 grounds for the motor and 2 grounds to the chassis and body. Heavy wire or ground straps. Rick L

Rick and Barry,
What happens when you have the coil wires and distributer wires running side by side in the same harness to the MSD? I have this situation and I am now curious about the negative effects. Thanks.

wrench87,

As usual, "it depends."

An oil-filled coil mounted horizontally atop the engine will fail. Now, if it's on a show car that will be driven a thousand miles or so in its lifetime, no problem.

My MSD Blaster II was mounted horizontally and left me in the most rural part of Florida I've seen - very beautiful but a long way to go get the trailer - at about 14,000 miles when it failed.

I bought an epoxy filled MSD Blaster II and so far, so good at 24,000 miles.

Electrical interference is real. Try the routing-wires-together layout and let us know what does or does not happen

A Standard Mustang restoration coil mount or the Ford Racing coil mount will work fine. --

you may have to trim one corner on a grinder to clear the valve cover.

I had a machinist buddy of mine fabricate a small block of aluminum with offsetting holes. The holes on my heads would not allow a directly vertical mounting of the coil bracket. On the fabricated bracket, two holes aligned with the head holes, and two others were shifted to allow a direct vertical mounting of the coil. I used a MSD chrome bracket that came with the coil. I also used 1/2" offset cylinders over bolts to space the bracket away from the head to move it further from the head heat source.

Sure, not original, but it looks pretty cool.

MaSnaka John I can't answer for Barry but in my case My Speed Pro ECU got some screwed readings on the inputs. This is way they twist the 2 wires to help remove and possible signal another curcuit then these wires can pickup or may become sensitive to. This didn't happen when the system was new, I had run the car for about 5 years and this popped up at the track. Found the problem my watch inputs on the laptop and seeing them change without any movement of the throttle or other things. I run the 2 wires under the intake, single plane through silver plastic conduit from distributor connection to the fire wall of the car. ECU is under glove box inside of car. The outter coverings of the wires break down over time and leak out EM voltage. It's like high mileage sparkplug wires, you will see white spots where 2 wires are against each other. In the right conditions they arch too each other and cause missfires or dead cylinders. Water from a spray bottle works the best for finding cracks in the casings. Beats the finger method, GOD that hurts, it could also kill you. Anyway See what Barry has to say------ Rick L. Ps John I try to remove any possible failures of componets in the car with rapping, clamping, isolating, and insolating anything that could cause a problem down the road. Learned most of this from other racers breaking at the race and seeing what went wrong. Rick

[MaSnaka]

Rick,
Thanks for the info. I ask because my wires are all in the same plastic conduit running side by side. It has always beem that way without a problem, atleast not an obvious problem. When the time is right I will re-route them. The learning curve is huge, I hope to be at the top of the curve one day.

Pictures of a proper set up would help explain this for a lot of people.

Would this be considered incorrect mounting of coil?

[RICK LAKE]

RedCSX1 Morgan, it's correct and have seen coils mounted on all different kinds of motors. If it's an oil filled coil this oil is used to control the heat in the coil and prevent break down of the wiring and hot spots. I know mounting a coil upside down and running it for a couple of hour does give a nice whienny roast under the hood. Not my car. Have always been told that straight up and down is the best way to mount. 45 degrees is better that laying flat on the motor. I think a 35,000 volt coil can be mounted anyway you want and have no problems if it's running a ballast resistor to keep voltage down to the coil. The new stuff with 50,000 to 85,000 voltages is a different story. Most of these coils are "E" coils and have no oil to cool them. This is why they need to be in an air flow of some type and not mounted on the fire wall behind the carb or air filter. Rick L.
