Coil OHM for 442 W30
What is the orig OHM spec of the coil for a '71 442 W30?

Have a new Pertronix 40011 12v 1.5 OHM coil on the shelf. Wondering if i should use.

UPDATE - FOUND SPECIFICATIONS
-Main PowerLine had a 1.35 ohm Resistance Wire
-Secondary PowerLine from the Starter had NO Resistance Wire. Designed to give the engine a little extra boost at startup

Looks like my 1.5 ohm Coil is just what THE DOCTOR ORDERED

That coil is meant for use with your Pertronix, why not use it.

Is the 1.5 ohm within the parameters of the orig '71 coil ?
I have pick up from a site that the orig '71 had a 1.2 ohm BUT i dont believe everything on the internet.

The Pertronix I or II can use the original stock coil, the module requires 12v but a ballast resistance is required depending on the coil used. See diagram below.
