HEI vs MSD comparison

The only thing I really like about the (basic) MSD is the multi spark that helps a good bit on low speed idle/cruise conditions as it helps clean up idle and helps the car to run smoother with increased mileage. This also shows itself on well hopped up engines.

On the race end, everything else about the ignition is a grey area for me as I haven’t found a margin of improvements that would have me do a MSD everything over any other well sorted out and strong spark ignition system. And that is the key. Strong spark! All the way up the rpm scale your driving.

I’m not trashing, faulting or claiming anything about or over the MSD. As a lot of what is used is also choice in what I’m doing.
