There were many of those type systems back in the past, Judson was another popular one. But when modern reluctive ignition systems came out in the OEM and then into the aftermarket, it's funny that all of those "great" ignition ideas disappeared. Because they were just a crutch, not an innovation or really viable reliable system.When I wrote "alternative" I was referencing the Mark Ten CDI system. Sorry I was not clear on that point. The Mark Ten was much less expensive than the real HEI system.
You seem from your different posts about cars and racing to be either someone that never did it or someone that didn't really understand(my guess from other statements in your posts)) what you read in a magazine. There are many like you.
