I got my 'new' 504 running and it works great! I'm having a ball with it. What i want to do is be able to test modern distributors on it as well. How would i go about making a modern distributor fire the xenon light? Any other improvements? thanks, oj
I don't have an answer to your query, but you might look here... http://www.jalopyjournal.com/forum/group.php?groupid=704
At one time Sun made an HEI adapter for them. I don't know if they are still available. I'm sure someone like GMC Bubba would have the answer. I'm sure if you could look inside one, it would probably be a pretty simple circuit to duplicate. Here is a place that has them. Kind of pricey. http://paramountd.com/parts.html
