HEI in Mopar ECU casing
Yep putting the GM 4 pin inside the old chrysler ECM box is a great idea if your car is already electronic ignition. Once its installed, it's a plug n play sort of deal. I used a mount plate by www.designed2drive.com for my 67 since I wanted to keep it appearing somewhat stock. I gutted a stock ballast resistor and soldered a 12G wire across, then filled in the resistor cavity with the wire using 5 minute epoxy.
Theres guys on fabo that are gonna Phoo Phoo you about using the GM module. I had been ridiculed by a few of em posting 4x4 camaro pix and people with billy bob teeth, and calling it a science project looking install. However you can use one and make the system appear stock, have faster cold starts, better idle quality, better acceleration, better fuel economy using the HEI over the stock mopar electronic boxes. I believe the stock GM modules are just fine up to 5,500 RPM. Above that they start to break up.
Also use either a GM E coil or if stock appearing is your game, spec out a pertronix ignitor lll cylindrical oil filled coil designed with a .32 ohm primary and a 45,000 V output. Pix of mine I made a 90° adaptor going from the mopar pickup to the GM module plug.
