I AGREE WHAT SOME PEOPLE DONT UNDERSTAND IS HIGHLAND HAS MOTOR LIMIT TRICITY HAS NO CUBIC LIMIT ALL STEEL ENGINE NO ROLLER CAMS HOW DO U COMPETE WITH THAT THERE AGAIN U HAVE TO BUILD A TRICITY ONLY BMODJmo, if you are a ump or allied sanctioned track, these sanctioned body's should have one set of rules that everyone follows, and not have the individual track change them. That way if you go to a allied track your legal at all allied tracks, and the same for ump. So you don't have to worry if I run at tri city and then go to a different ump track if the rules are the same.
