Unless you're trying to build some sort of 100% original show truck, the fix for a 292 is to install the HEI ignition distributor that's on the later model 250's and 292's. Your electrical system is already 12 volts, so the only other modification needed will be a #12 or larger power wire from the ignition switch to the distributor. HEI's were invented to meet the government requirement that any system that has an effect on exhaust emissions must be able to run 50K miles without being serviced.

That is the end state plan here, but I actually wanted to start on points. I want to spend the first year or so on points to learn it inside and out, and then when I switch to HEI the points will go right to the glovebox so if I ever have a problem on the road, I can swap the points back in and get home since points can be jerry rigged and repaired on the roadside, HEI cannot always be done so.
I understand most don't like points, but its where it all started, and I want to know that system inside and out, even if it is just to truly appreciate where we now are without it. Call me sentimental I suppose; born a couple generations too late.
