Somehow, I just can't picture him installed in a blown Hemi on a dragster. He'd ruin the streamlining, and make it hard to see to steer.https://en.wikipedia.org/wiki/Ignition_magneto
Quick tutorial. In the 40's and 50's you found hot rods using this system on the street. They were a quick way to gain ignition ability at extended rpms, and fire mixtures of fuel and air at high compression. Back then, anything over 4000 rpm taxed the ability of manufacturers distributors and coils. Problems arose in that the easiest way to start a magneto equipped V-8 was by push-starting it. I can remember asking my dad what was wrong with a really pretty hot rod, about 1954. He had parked on a hill, and rolled down it to start. We talked to the man, and he showed me his Flat-head equipped with a Harmon-Collins magneto.
