GM HEI conversion questions

Ok got it, I think.
The GM ECU is cheaper, and probably actually easier to get.

And you are saying that if you use a GM ECU that you can put a full 12 volts to the stock coil without it overheating?
If so, this is the part I did not know.
Just trying to be really clear on that point.

At O'Reallys a GM module is 25-50 bucks depending on source, up through Accel, and Mallory is 57 dollars

A Mopar ECU is 22--50 bucks but they are UN branded until you pay 60 or 66 for an AC Delco

And at NAPA a Mopar ECU is 52 bucks

NOBODY around her sells Blue Streak anymore, I'd have to have one shipped from Summit or somewhere, so over 50 bucks by the time I get it in hand.

With all the stuff I've read about Mopar ECU's puking potting material out the case, uh, thank you very much.

And yeah. eliminating the ballast is just "one more thing."

Sorry, I just don't agree with your "all or nothing approach." There are more than one ways to skin a cat, or so I've been told. For me, this was economical, easy to deploy, and has been reliable. While temps here rarely get over 100F, we do have summer days into the 90's and high 90's, and I've been on several long afternoon outings
