New Coil

[tsanborn]

Hi All-

Can someone tell me what internal ballasted coil I should be using on my 292 Y-block.

Many thanks,

Tom

A black one, I like the Bosch blue with a light coat of black paint

Should we assume you're wanting to eliminate the stock ballast resistor & its related wiring?

You will want a coil that measures 3 to 3.5 ohms across the two small terminals. The Bosch blue coil is a popular choice.

The Bosch blue coil was always Buba's (RIP) choice for a coil. Unfortunately they have gotten pricey as of late.

FYI, the ballast resistors were used on 1.5 Ohm primary coils to allow them to function reliably on 12-volts. 3.0 Ohm coils were not available till modern materials, ie epoxy internal insulation, caught up with ignition coil technology. They used wire wound resistors in a heat resistant ceramic block in those early years. In the late 50s and on, they started using a resistance wire that didn't generate near as much heat to control the amperage to the primary coil. The 3-Ohm coil works fine on 12-volts with no external ballast.
