I quoted both because it applies to both posts.
(to agree with one and not so much the other.):D
The HEI has benefits over a stock spark in more than just performance.
It makes cold starts easier because of the hotter spark and not getting the spark pulled down near as much with high starter loads and a little better fire for situations like too much fuel from overchoking.
Engines tend to run smoother, and have a more complete burn of the available air/fuel mixture.
It adds to drivability, increases fuel economy and is not a waste for anything but racing in my opinion and experience.
And if we think about it, a person could run an E or C core coil with points if they wished and get real close to the same performance.
This means that it's not really the HEI part per se that makes the difference, but the coil spark strength.
(which is exactly the same thing points running drivers that put on a big Accel or other brand performance coil are doing)
So the fact that HEI is really only the control module we are basically just discussing the difference between a stock spark and a more performance oriented spark that does have real world benefits outside of racing.
