Richard, have you informed General Motors of your findings? They could have saved millions of dollars over the 20 years or so they put heavy wires on HEI ignition systems if they had just asked for your advice. When installing a HEI in an early vehicle, it's necessary to upgrade the wire size all the way from the fuse link connection at the starter terminal, to the ignition switch, and then to the distributor- - - - - - -just like GM did it when they went to HEI ignition! You're neglecting to consider the inductive reactance of the coil winding in the equation, which draws nearly dead-short current for a few milliseconds while the coil primary is charging between sparks. Get your facts straight before you go offering incorrect opinions.
