Ignition problems.

Okay, it's been a while since I made an update on the HEI conversion problem. This one is a bona fide "how'd that happen".
As you'll recall from earlier, I followed an article from slant six forum on how to put an HEI system in a Mopar. Well, I'd been having no success re-reading and rechecking my wiring, making sure all was right. And it was. But no spark.
So long story short(er) I pulled my distributor again, wondering if I should just go back to points. While I had it out, I noticed the mark on my old dist. that I had put on there to show where my timing should be set. So I took the time to carefully place the mark in the exact spot on the new dist. before putting it back in and once more double checking (for the fourth time) that all my connections are correct. I also added some extra ground wires to a couple of the components.
Hooked up the battery, dumped some gas in the carb, and turned her over, expecting the same result. But by God she fired up! But I have to keep feathering the gas to keep her going.
Today, I got both my boys to help me out- one to keep her going on the gas, one to run the timing light, and I was twisting the dist. My son on the gun helped me dial her in, but she still dies when left to idle. Still scratching my head, I noticed that a connector to the relay had disconnected. "Well there's the problem!" I thought, and corrected the connection.
"Okay Mitch, try her again", I said, and when he cranked her over, no spark! What the Hell! I thought. So I disconnected the wire that I had corrected. And didn't she fire up again!
Well now TOTALLY perplexed, I went back to the article. I had to have done SOMETHING wrong! It was then that I realized there are two different types of relays. The article calls for a "normally open" 4 prong SPST. I had installed a "normally closed" one. If that EXACT wire (of the 4) hadn't disconnected, I think I'd still be trying to get spark!
So now I'm waiting for amazon to send one to me. Hopefully, this will be the answer!
