the problem was that the intake gasket had been messed with to keep if from actually sealing the intake which allowed it to "Air Leak"...which would simulate having a bigger carb by increasing the airflow into the cylinders...if you jet a small carb rich and pull air in from somewhere under it it has the same effect as running a bigger carb...

This trick probably started in go-kart racing where people would slightly bend the restrictor plate then loctite the carb bolts in without tightening them up in order to suck extra air in behind the plate...

I'm not sure exactly what Newmns team had done but I do remember the report on speedchannel stating that the intake had been modified to pull air in under it so it had to be something along those lines
