Every sanctioning body has rules governing ignition systems. RacingJunk is going compare two HEI distributors and two CD Ignitions that most sanctioning bodies allow.
Ignition systems and their components have changed immensely over the years.
When we last left our ignition project, the distributor was pretty much buttoned up and we were down to the final setup.
This time around, we’ll look at the vacuum advance system in the distributor, along with other details.
With this segment in our series, we’ll finish stripping the distributor and then we’ll go to work on the mechanical advance system.
For greybeard hot rodders and racers, it seems it wasn’t that long ago that hopped up point trigger ignition systems were the standard for performance. And with the right mix of parts, a vintage point equipped distributor can be rebuilt and reworked to act as a trigger device for a modern high ignition system such as an MSD 7AL2.
This article will cover the more advanced features of the Sniper unit, including the built-in ECU.
Join us for a look at several common MSD coils suitable for drag race only as well as street-strip applications.
Ignition coils aren’t really that complicated. Neither is the job they are tasked with, but in a high performance or outright racing application it can become a little bit more complex.
In our last issue, we examined MSD’s unique Flying Magnet crank trigger system.
