OK... my MSD Blaster 2 coil took a dump on me this weekend and I had to get her running so I bought an oem style coil from Napa for $20. I am running the MSD 6A ignition also. It seems to run fine and I just wanted your expert opinions and see if that stock coil is going to be a reliability issue with the combo I have. I don't have a problem ordering a new MSD coil but if it isn't really needed I will just leave it alone. It isn't a beast but does have an Edlebrock performance kit.... intake, carb, cam etc. 351M. Thanks guys.

 

I would look at the MSD instructions that came with the box, or look them up on MSD's website. See what they say about the coil. I am sure they will pitch their coil as being best, but see if they say anything about using the stock coil.

 

Thanks Franklin. I did look it up but it doesn't say anything against using the stock coil. I emailed them too and still waiting for a response.

 

I'm running a stock Ds2 box with accel coil, and wires. We removed the original coil in the tuneup we did. I seriously hope my tach works with this aftermarket coil.

 

OK, let me ask this. When I go back to a DSII ignition system, do I use internally ballasted or not?

glovemeister, which Accel coil did you get? (model number if you can)

 

Hey bud I got this one 8145C superstock chrome. However if I had it available I would have gotten 140207 specific for the duraspark ignition. It even has the horseshoe connecter and I wouldn't of had to cut my wires and wire them to my coil. As a result I am not sure if I lost my tach function or not, but I am sure that I can back wire it somehow. I will just have to see.

 

Is that an Accel also?

Oh, and about the ballast question...?

 

If you use your original factory harness to feed the coil +, you do not need a resistor, it's built into the harness.

If you have modified the harness, or are using a different hot wire to feed the coil +, then yes you need a resistor, either one built into the coil, or go buy one of those large white chrysler coil resistors and mount it on the firewall.

The DSII system does require 1.05-1.15 ohms resistance in the hot wire feeding the coil to limit the current through the coil and the DSII box.

 

Yep both are accel numbers pulled from their website. I suspect that you would want internal ballast, atleast thats what I run and have no problems.

 

Thanks! I'll file that away for future reference.

 

@Franklin2

The Accel part number Glovemeister provided for the DSII coil is here:

Accel 140207 Racing Coil Ford DuraSpark

This is what always confuses me. It doesn't mention resister needs one way or another, or does it? I'm not sure if I know how to read an ad like this one. What is it that I'm looking at?

Could you explain it a little better for me?

Thanks!
