TFI Coil

i have used a lot of brand "A" parts and was left shortchanged. after a lot of testing on a scope, i could not get any more spark energy out of a supercoil than out of a factory motorcraft coil. considering what one costs, dont waste your time like i did. MSD has better quality coils at a better cost, dont require special mounting like the supercoil, and are more reliable. MSD also makes a good tfi coil as well. you may not need the springs right away unless you have made changes to require different timing characteristics.

*Peanut* asked,
*Ok, let me get this all right in my head now. For the upgrade on the 304 or 360 I will need to get a cap and rotor for a F-350 and a TPI coil for a 83 F-150 with a 302??*

One more time, but only for a fellow grunt...

You are getting it, but you need the Cap Base, Cap, Rotor & Plug wires all at the same time from a '79 Ford F-350 Truck with a 460 CID engine.

If you choose to upgrade the ignition coil at the same time, use the TFI (Thick Film Integrated) coil from a '83 Ford pickup truck with V-8 anything.

*Am I right???*

You're getting there...

*when I get all this stuff do I have to change those advance springs or can I leave it the way it is????*

You don't have to change the advance springs ever if you don't want to. It's just a low cost (but high effort) way for motor heads to get a little more zip out of the engine, and the improvements in gasoline from the late 70's.
Some people will do it and change back because they use crappy gas, or have a lot of crud built up in the chamber and on the valves, and all the spring so is make the engine spark knock. Like I said in the article, it's the next step in upgrades after the Cap base, cap rotor, plug wires and coil...
----------------------------------
*I just want to get all this stuff right when I go to the parts store.*

Calm down Ranger, this is hobby stuff, not anything really important... not like Like Best Ranger Competition...
----------------------------------
*How is the Accel Super Coil compared to the TPI??? Is it just as good or worse???*

TPI is Throttle Position Sensor or Tuned Port Injection.
I'm talking about ignition coils. TFI. Thin Film Integrated.
TFI coils are better than the Accel Super Stock coils or the Accel Super Coil for your application.
The Super Stock coil is a little better than the average 1980 coil it was going to replace, but can't hold a candle to the TFI coil.
The Accel Super Coil, (A great big yellow ugly mess left over from the 60's that hasn't died yet) isn't even supposed to be used with your DuraSpark module.
The point is moot anyway, the TFI coil kicks it's butt also....

tpi coil?? what am I doing???

man i guess i am not with it tonite/wwwthreads_images/icons/tongue.gif

as far as wires, i would get a set of universal MSD superconductors. this way you can cut them to length and have really good wires to boot.

Re: tpi coil?? what am I doing???

I'm not a fellow grunt, but I wish I were. I had planned to do the HEI upgrade this summer but I'll do this instead. It sounds like as long as I don't change the Distributor Advance Springs I don't need to pull out the distributor? Will there still be an improvement over HEI if I don't change the springs? I can't wait to see this on an instruction page with photos. Thanks TeamRush for being patient with us/me.

It's the SQUARE TFI coil you are looking for.....
The F-350 with 460 CID engine in 84 should have the TFI coil, so the plugs wires for same should work with the TFI coil.

The original post with 79 Ford 460 CID plug wires were for the canister coil.

*the MSD harness p/n 8869. I was going to order it today but the less then helpful guy on the phone told me this was not they way to go, but could not enlighten me as to why. He said that on a Jeep the MSD unit should simply go between the stock coil wires and the coil. Cuase dats what it says in da book.(of course I didn't believe him)*

What guy on what phone from where?
The only way you use the MSD in between the coil and coil wiring is when it's a computer controlled vehicle. By just firing off of the coil input, the computer still can control the timing functions.
(If it's the guy from MSD, he has to tell you the way to hook things up to keep the emissions stuff legal. He has no choice, it's the law.)

If you don't have a computer, or have it disconnected, don't listen to a guy that hopes to be on fries at Burger King one day... You gave him a ford part number and said Jeep, and it confused the two surviving brain cells he had left...

The Adaptor P/N 8869 connect the Motorcraft distributor to the MSD module without cutting any wires on either.
(That means in a pinch, you can plug in the DuraSpark module, and get home. The Dura Spark will work with the TFI coil... It also means you can still use any parts from any parts store...)
