New Q Jet

My first concern, one of many, is the legality of these carburetors for NHRA Stock and Super Stock use. The engine blueprint specification sheets only list Rochester and the Edelbrock replacements, which by the way gets a +.015 primary venturi size upgrade over the Rochester. Until NHRA makes an official call on these, I wouldn't recommend any one purchase one with the intent of putting it on a Class car. If they were to be deemed legal, I would be glad to perform an in-depth autopsy on one and post my findings here.
