Another HEI Application

As my '55 Pat is a daily driver and I do rather a lot of highway driving, when I started on it four years ago I installed the Pertronix, 12v, positive ground ignition module. Realising that I'd be hard pressed to find another on short notice, I bought two of them and threw one in the glovebox. It's still there.

About four months ago, after a round-trip from Orlando to Miami and back, I decided to try to improve my fuel mileage a bit and purchased a Jacobs, multi-spark ignition system and installed it, along with a 65,000v high amp output coil. Purists will probably object to this but the system can be hidden/camouflaged, if desired, and truly improves both performance and fuel usage. I looked at several MSD units and chose the Jacobs primarily because of its price compared to others. It does what I need it to do, was easily installed and works VERY well for the price.

I have wondered for the past several years why MSD systems aren't built into modern ignition systems. It would seem that, in modern applications, all they'd have to do would be to use a hotter coil and program the onboard computer/s.
