Bridgeport SCCA classification??
 

If I perform (or have performed) a bridgeport on my 1990 GTU N/A, what class will that put me in? Does it fall under internal engine modification? I have seen where on some types of racing, different types of ports will put you in a different class.

I didn't find anything on this search or on sccaforums, so I gotta ask.

Auto-X or club racing?

I'm sorry, SOLO II for the most part.
