Once it dies I'll switch the whole system to Pertronix flamethrower

I've got a Summit ignition box ( https://www.summitracing.com/int/par...illocation=int ) on the way. They're supposedly made by MSD and certainly less $$ - $148 for a digital box with rev limits. I think the closest MSD box is a 6AL for $100 more, though the 6AL appears to be a bit more efficient, with slightly higher output and slightly lower power consumption. My engine is a relatively mild build, so the lower output of the Summit box is pretty much irrelevant, IMO.

The box is not going to be mounted in the engine compartment like the old MSD box was, this one is going behind the dash to keep it a bit cooler.
