Billy, on one hand, you are correct in that both instances are a somewhat fundamental change in the current rules.

However, for NHRA to adjust the cylinder head volumes because they told the racers a year ago they could legally do a more radical valve job in no way compares to NHRA allowing an OEM to hire a tuner to bring in a supercharged non factory production car.

The adjusting of the cylinder head volumes, if it happens, is a result of NHRA having to compensate for poor decisions they made, not only is it possible, even likely that their list of volumes has some errors, but before deciding to enact a cylinder head volume rule, they first allowed modifications to the heads long after the volumes were established.

This other train wreck, well, it pretty much speaks for itself.
