True HEI distributor conversion thoughts

Frankly I don't like "big cap" HEI, mostly because it's harder to troubleshoot. What happens when you want to check spark? How many questions are on here turn out to be a "poor spark" problem, either low supply voltage or a bad coil or????

I've SEEN (original GM) HEI with bad coils, various carbon cap tracking or rotor punch through and NOT ALL of these were incredibly obvious!!!

There are several ignition systems you can trigger with a Mopar magnetic distributor, and there are a few breakerless aftermarket distributors. The "ready to run" Skip White small cap ones seem to be OK, a number of guys run them

THEY ARE NOT HEI which to me means GM HEI. They are a 'down under' I guess Holden? module, and again, seem to be "OK" in their own right
