I installed a Mopar performance electronic distributor with Chrome box ECU in my 1970 440.

I have the following Accel 8140M ignition coil:

Super Stock Universal Performance Coil

SPECIFICATIONS:
Color: Yellow
Maximum Voltage: 42000
Package Quantity: 1
Primary Resistance: 1.400 ohms
Secondary Resistance: 9.2K ohms
Turns Ratio: 94:1


From the info above coil specs I assume I should be running a ballast with approximately 1.4 ohms. I currently have the original points style 0.6 ohm resistor installed. I am thinking I may be asking for trouble with the coil overheating. Should I upgrade to the 1.4 ohm resistor? If so, what brand do you like?

I see these models are available at approx. 1.4 ohms:

NAPA* Echlin* ICR11 (1.35 Ohms)

NAPA Echlin ICR34 (1.4 Ohms)

Lucas* 3BR (1.3 - 1.4 Ohms)

Mopar* DCC-4529795 (1.4 Ohms)

Accel* ACC-150250 (1.35 Ohms)

Standard* RU-4 (1.35 Ohms)

Standard RU-23 (1.2 ohms)

Standard RU-37 (1.4 Ohms)

Thanks in advance for your advice! Joe
