dwell in degrees is not dwell time.
at high rpm the degrees is very long but time is short.
In the old days they ran points and the coil was designed to run huge long dwell times at idle (or worst failed start cranked and points landed closed, and not burn up (unless a 1968 VW , lol) a CHevy V8 (1965) had ballast restore to end key on coil burn ups. BUT BYPASSES CRANKED.
then at say 4000 RPm spark was still good.
then EFI happened.
and the dwell time is now dynamic. and the coils run why higher primary currents for 2 reason, it should and we can for more spark power.
and the coil can burn up easy, if you dont know the coils spec. modern. (Custom EFI)
