Anyone using one of these coils on their A-body???

-
Going to run a coil off a mustang for a tfi module as we are running a stock electric dizzy and hei module on the 360 Mag in the Coronet. I know that doesnt help but I know most of my newer coils get 12V to coil.
 
OP needs to specify what ignition he is running. You running the Mopar box? You can get away with no ballast on an HEI module because they work quite differently than the Mopar breakerless. I ran a 4 pin HEI with a bone stock 67 Mopar coil, no ballast

I've "read" where some had used these. Just wondered the benefits, and if they required a ballast resistor.
 
It seems like when choosing coils they go by ohms. 3.0 1.4 1.5 .6 etc. Chrysler electronic ignition normally uses a 1.5 ohm with a ballast resistor.
So I would think the this newer style coil can work as long as the ohm ratings match what it necessary for the type ignition you plan on using.
I have been playing around with different ohm coils as of late to see if any gains/losses to how the car runs. I tested a 3.0 ohm coil with a 360 swapping out a lean burn to a Chrysler electronic ignition with ballast removed. Car ran great, eliminating the hard hot start that the car had before with the 1.5 and ballast.
I looked at the coils you posted but didn't see the ohm rating.
 
I think that coil has about 1 Ohm primary resistance. Coil may over heat, even with 2 Ohm ballast, since mopar ecu does not properly control dwell. Coils like that are for ignitions with active dwell control like HEI, or real computer timing.

I don't see what's so wrong with the Mopar electronic ignition. Oh well.
 
It will work fine with can coil. Put it on an epoxy coil it will over heat coil. In picture above the cross hatch area does nothing, but heat the coil and ballast resistor. The HEI, predicts where to start charging coil, so it happens just in time for use. Keeps coil, ballast, transistor cool, saves alternator draw.

Neither do I, I wish the van I bought had one. Unfortunately, when they eliminated the TBI they used one of the Chinese "ready to run" distributors. Thus the reason for this thread.... trying to learn :)

Gotchya. So it's been converted to carburetor then?

yep. That part I like. How they ignite the gas I don't like.... although it runs great. I can't stop at any parts store and buy anything for the distributor should something happen. I don't like that....

Why not put Mopar stuff on it? Or the GM big cap?

the TBI has that big, ugly, black computer box under the hood. They are using that, yet brought power out to the coil, which fires this 54 dollar ready to run special... LOL. I'd really like to go points, honestly. Just not sure how to wire in a ballast and what coil?? or can I run a coil with resistor in it and no ballast.... I'm trying to learn some options....

Just find the 12V wire and run with it......act like everything else isn't there.

run the 12V wire to the coil with resistor in it .. for points? I know the regular Chrysler electronic ignition needs the ECU box. I love to run points, and carry a new set of blue streak in the glove box.

I like points, too. If my 75 Ford had come with them, it would have a point distributor in it. Yes, just take the 12V source that goes to the distributor NOW, run it through a ballast and to the coil and then the distributor. I would make sure that 12V source IS a 12V source if you know what I mean.

I'm not understanding completely, I don't think. Why is the "black box" even there anymore if what it controlled is gone?

Thanks, what you've described is kind of what I had in mind, using a 2 prong ballast. I believe the ignition and all runs through it. Problem is, the guy who did all this had a much better understanding of electronics than I do... LOL. which don't take much

If the black box was only to control the FI, then I would rip it out and throw it in the ditch where it now belongs. All you need do is find the 12V source that feeds the box, and use that as your coil positive going to the ballast and throw the box in the ditch. It's not doing anything anymore.

lol... you say it just how I feel. When the weather turns better for us, I plan on trying what you said. I ordered a new points distributor. Thanks RRR

You bet. Yeah, the weather blows chunks here. It's been WET as all get out. Now it's drying out a little and getting cooler, which is fine by me, but now I'm sick as a DOG. So there's "THAT". I think I may get out tomorrow and at least tear this 400 down.

I just went and looked at the pictures and it HAS the GM big cap distributor. So.......WHY are you wanting to change it?

yeah, I guess I've never owned one. Are parts readily available for these at any parts store? I guess I was looking for something that I was more familiar with.
