Setting of the spark that ignites the combustion in an internal combustion engine can be a tricky thing if not all the perimeters are in line. Although keeping your muscle car old school-cool and purposefully low tech is quick becoming a growing trend, it doesn’t mean that your engine needs to suffer. The guys over at Street Muscle Action went to the engine dyno to take a closer look at what makes ignitions run their best.

Requiring a single wire for installation, its clear that keeping your old HEI might not be all that its cracked up to be.
