Could some one tell me where in the fastcar rules does it say you must weigh 2950 pounds with a stock crate motor with 1.5 rockers?The tech person told me you must weigh 2950 pounds when your motor has been rebuilt and sealed by your local tracks tech guy using all the stock parts on the zz4 350.The only rule I see is that if your using 1.6 rockers and comp cam springs you must weigh 2950
