Thanks Tony!
I would have to make changes to switch, or I would remain in my class. I just wasn't sure if the changes would change just the car classification, or if it would change the engine from XXO to a 'C' engine. I wasn't clear if electronics weren't allowed only on Vintage classes, or vintage engines i.e. XXO.
I have sent the question to the proper officials, but it takes a while to get answers, especially with El Mirage and WOS this week.
