reading the 2009 nhra rulebook for stock, under pistons, there is nothing saying this is an illegal part. as long as there is no mods to piston to run ring, its legal. and to think, somebody has thought to finally build a ring just like this. i do know of a few people, whos names will remain nameless, that already use these rings that they have customize. there are gains to be had, depending on how cylinders are prepared. rick.
