Which ignition system to use?

I would look online and buy a used Mallory 6 and be done. Not a big fan of the FBO stuff.

MSD is a crap shoot.

Make sure the Mallory box LOOKS like Mallory box and not an MSD and youll be good to go.

If you are still using points and dont think you are giving up HP you either have a low output engine or something is wrong. Most points sytems hit the 350 HP point and thats all they are good for.
