1975 Cadillac Calais Performance Ignition Products

Engineered for faster rise time, longer spark duration and increased performance. Unique design with premium grade wire, special low resistance, high turns ratio windings. Produces higher spark energy with breakerless electronic ignition systems. For points application the supplied 0.85 ohm ballast resistor must be used in conjunction with the vehicle original ballast resistor, if so equipped. Oversized molded case with integral cooling fins and high capacity oil filled construction provide high thermal conductivity ensuring cool operation and long life. Extra tall tan Alkyd tower and integral voltage dam eliminate “flashover” to primary terminals. Comes complete with mounting hardware and 0.85 ohm ballast resistor. Effective up to 6,500 RPM.

HEI owners now have a choice to replace their stock coil with the MSD high energy unitized coil for GM HEI distributors. This coil is a direct replacement of the stock coil and offers increased spark energy when used with the MSD HEI module, PN 83645. The coil features special low induc?tance, high temperature windings which charge faster to give you increased spark energy at higher rpm. The premium epoxy filled construction is designed to withstand harsh race applications as well as the wear and tear that daily usage dishes out, and still deliver more spark energy to the spark plugs.

Product Features:

• Direct performance replacement for GM HEI coil-in-cap dist.
• 70:1 Turns Ratio
• Lower Primary Resistance Produces High Voltage Output
• Full Power Sparks To 9000 Rpm w/PN[83647] MSD HEI Module
