Factory experimental

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.

Alan, when the SS runner volumes were originally posted they were somewhat enlarged at that time. What we NOW have is a specific number for NHRA to use as a tool to better do their job. Too big, too small, it's a number and we can't exceed that number. Just because the rules say that you can "pocket port" your "Stock" head and use a "backcut" valve doesn't mean that you have to. I've been getting told that by the "genuises" in this sport for years. If your head measures too big then I guess that you'd better put a thick valve in it or start fresh and don't get so "piggy" with the bowl hog. I will say again, "we have all brought this on ourselves by allowing a perversion of the rules for years".
