I'm currently using a Mallory ignition, with CD box. It has mechanical advance only. It does a pretty good job. But with such a radical engine, I'm pretty sure it will run better if I can get better control of the ignition events. Since I want to upgrade the computer anyway, I figured I could kill two birds with one stone.

My peak HP and torque is right around 6,000 rpm. It will still make power above that, just not as much. I currently have the redline set a 6,400 - that matchs the hydraulic roller cam. But I'm seriously considering a solid roller cam for the next overhaul. Although I can't use it today, I want an ignition system that will handle 7,500rpm's.

I always carry spare ignition parts for the Mallory. Failures are not uncommon. I'd like to use something more reliable.

Besides, upgrades like this are fun!
