I'm sorry to get you upset. I am not trying to start anything but I am saying formula racing. Where you have a set of guidelines to stay within. It covers a broad spectrum of racing. Say you have a maximum of 355 cu.in. but you have a 350. Boring it .030" over will get you to the limit. I understad it is uncommon but it does happen.

About the porting thing I just wanted to share my experience with others.

Again I'm sorry. Have a nice day everyone.
