More Distributor thoughts

I did just have one more thought on the distributor thing.....

For engine damage to happen, the spark would realistically have to jump
past the current post, and light off the next one (leading edge). If it
were to light off the previous plug (trailing edge) that should be a
moot point, since that plug just fired 144° ago relative to the
crankshaft. It's still on the power stroke with the exhaust valve
opening soon.

Firing off the *next* plug would probably be just after the intake valve
closes, which could be a problem...If this was the likely scenario, then
people would want to file off their leading edge :o)

It seems that the real solution to this confusion would be to eliminate
the distributor all together. Maybe I should design that coil-on-plug
conversion for the 20v after all :o)
