The advanced engineering for the HEI ultra performance module #110-35367 has been repackaged into a smaller size to fit inside the bowl of Accel electronic breakerless distributors. The high amperage dwell circuit ensures full coil saturation for high RPM performance. Surface mount electronic technology maximizes efficiency, output and reliability. Accel #110-51000, 61000 and 71000 series Electronic Breakerless Distributors are equipped with this module which operates on 12 volts, so there is no need to run a ballast resistor.
