If we are then how does this affect the "replacement Holleys? Do they have to use an OEM Annular Discharge booster or can they continue to use a Down-leg booster? How about throttle shafts and blades? A little more of a heads-up here guys. I don't like surprises! And I REALLY don't like ambushes!

Agree. Policies have been inconsistent and clear as mud.

Let's go back some years ago when NHRA started bouncing people with Quadrajets that appeared to be polished or did not have any casting flashing. Still remember showing NHRA Tech, a brand new Quadrajet, still sealed in the factory wrapper. I just had opened the box and they unwrapped it themselves, when they looked at the venturis, there were no flaws and they looked perfect. I asked them if the carburetor would be illegal and they were perplexed that a new carburetor would look that way.

All I said was, "how about if the manufacturer changed their process for cleaning castings with a new method and this happens to be the result? Is it the racers fault? How about developing some criteria and share what is acceptable and what is not? All they did was to take some pictures of the carburetor and no answer to the issue.

It also appears that the casting finish inspections by NHRA on carburetors stopped when all the newly approved replacement Edelbrock and QFT carburetors were made available.
