Something to think about.... The ignition system already includes a high
current transistor designed to put pulses through the coil.  Use the 555 to
drive the lowpowered input to the HEI ignition module, rather than just
using the coil  I haven't researched this recently, but it seems that the
ignition module (the part between the pickup coil and the ignition coil)
should be readily available cheap (possibly as part of the system on the
distributor?)
