A lot go for a so called group a coil, these definitely improve matters spark wise, as are a bit higher energy.
Some have fitted the MSD blaster coil,(not msd uk), there is also a aldon one that can be used to good effect.

Thanks tabetha, good to hear from you again. Where can I locate/test this primary resistance? I can of course replace it with a new one? In your opinion is this coil (Standard (USA) FD78X, is used for Fords) okay? I am asking because I canīt buy the original coil here, but this one I can buy quite cheap.
And if the one I have is okay, how can I test it?
