After reading all your posts, I'm put of getting a MSD or any other box ignition. I really wonder how much more power it produces opposed to a simple electronic dizzy and Accel supercoil?

Yes, CDI does have 500-550 volts at the coil, BUT the coil is used as a step-up transformer only. It does not saturate then collapse like inductive ignition does.
That 500 volts is also only about 20% of the discharge time (versus crank degrees) of some factory HEIs and some "decent" aftermarket electronic ignitions.
Factory HEI has "high voltage" at the coil negative terminal.
I have some mates with MSD, but I still have doubts about their products.
