The coffee cup is empty. Time to get productive. Must look for ZKX's coffee shop while out. 
Stop in for a cup of coffee

If you find it, let me know where it's at. LOLThe coffee cup is empty. Time to get productive. Must look for ZKX's coffee shop while out.

define efi! You mean fuel injection or ignition?
Nice article! Pretty much explains it way better than I can
Good adventure on a score roll again today, Pick up smokes the rep is there gives me coupons for 4 off a pack, then stop by Keiters farm junkyard just to drop off some old tools I had for the wall of his new shop, well might have a 50's Packard TBD have to look at it supposed to be a hemi drove by it a lot looks ok just have to see how it really is. I need to play the lottery for sure this week! daughter bought brunch, had a good time at the yard also! Winn win for all!
This might be a stretch! 1973 Dodge Dart for sale near HARLEM, Georgia 30814 - Classics on Autotrader
Was wondering the same thing...
Yep you need to buy a lottery ticket!
Prob tomorrow for Powerball!
EFI nowdays can control the injection and the ignition.
I always referred to the Mopar as EIS?
Dam spit it out then!
Might have both? Maybe he will show you his!
Oh one more they have a slant six combine coming in might have a aluminum engine, asked if I want it?

ive thought about using EFI on the poly.
Aluminum probably not. Is it a Oliver?
But then I would not have gotten it in the first place, 4 doors...
Lots of choices nowdays. They work well. Heck, I had the old analog Holley system on my tool truck 10 or so years ago. It worked well. I liked it because all the adjustments were on the control box under the dash.

I have an 'extra' steel slant I'll trade you for it.Oh one more they have a slant six combine coming in might have a aluminum engine, asked if I want it?

problem is the money involved.
Agree but they really are misleading people into running without a ballast resistor when they should.
They also skip how it works - cooling off at higher speed thus allowing more current at higher rpm, and that compensates for less time available to saturate. This is right out of the Chrysler tech bulletin on pages 4-5
Ignition System Analysis 1969
And again in the era electronic ignitions
from 1972 MTSC Ignition Service (Session 292)
If it wasn't needed, Chrysler and Ford would have saved a heck of a lot of money. LOL. GM's HEI module controls the current. Can't tell you how many guys on the IFSJA forum had problems after following the 'hot tip' for swapping in a "TFI Coil" and bypassing the resistor wire. Works for bit, and then it doesn't.
Only partially correct. Single ballasts were also used.
The dual resistor was to protect the ECUs as explained on this page
1973 Chrysler Electronic Ignition Diagnosis and Repair (Session 312)
So removing a the ballast resistor on those Chrysler boxes will send them to an early grave. I'm sure the magazine will give those owners a refund

True that. Many don't know about the resistance changes with coil temp/time and the purpose behind the design.Agree but they really are misleading people into running without a ballast resistor when they should.

The most important thing it does is reduce the voltage to the points/coil to prevent arcing and extend life. 6 volt systems didn't need resistors.
