10Exactly. 2)Exactly. 3)Well, there are the rules and like anywhere else I'd guess there is a matter on how they are interpreted. My INDY S/R 485" with 2 4bbl would be about 2830lbs. Weight breaks for Mopar=-125lbs Teir2 Body=-50 Then a penalty for 2 carbs 10% of CID again about 2830lbs total with driver of course. (EDIT: 480CID is 2940 base weight)
