Model T Drag car.

With the mechanical injection I'd run the magneto. Vertex or Joe Hunt.
MSD is just a multi spark electronic ignition that you can't even put good
copper core cables on without it going to hell over the rfs. Then there's the graphite spiral bull that wont last or even come close to copper as a conductor. Their only used because they don't generate the rfs and they can sell a lot more of them cause they dont last.
MSD has its place in racing with electronics. Snooozzzz.
Doesn't belong in any vintage or nostalgia racing.
