To those who need help, rotate a mag, then rotate a distributor.

Instant
drag, and a great difference in spark intensity. Then check the spark
gap recommendations on each. There IS a reason why a wider gap
can be run in late model autos. We quit using mags in racing over
twenty five years ago. A 5000 hp engine today is fired by twin
electronically fired and controlled distributors. Sometimes
referred to as mags.
Ideally, a crank trigger mechanism is even better due to the more
positive timing.
My one and a half cents worth.

BTW Cadilac went to a lot of trouble getting the spark trigger
in the center of the cast iron crank to minimise the effect crank
twisting has on spark timing in the Northstar V8.

So even if you use crank triggering on a piston engine a 
lot depends on where along the crank the trigger is 
physically located.

Fortunately the two rotor eccentric shaft is very stiff
so we don't have those problems.
