Agreed. But like the heads...how would they determine what's 'stock'?

Sounds like Wesley will be at Indy.

I think Wesley will be at Indy.

The question I have, with the lack of tech officials and man power how did they possible get all the heads scanned, there has to be hundreds of heads used today. Shouldn't they have told Stock and Super Stock this will be the new standard. Also when scanning, do they take into account core shift. I also heard this was a major concern with the Showdown cars, maybe that's the reason for the low car count for Indy.

Interesting topic and I would like to here more opinions good or bad.

Unfortunately I had to delete the email as a request by the sender. In my opinion we should know whats going, this is why I posted it. Although I am a D1 racer I don't receive emails from the D1 rep because of my affiliation with Class Racer, draw your own consultations. NHRA has made their own announcement on this subject.

This sounds like something from the past.

At the Sportsnationals, in the late 70's, there was a sign posted on the return "road SS/AA turn here".
NHRA did not, at that time, disqualify any cars. They did learn a LOT about the cars by having them all sitting at the same place, at the same time. I expect it allowed NHRA to determine the cars that were constructed to the extremes of the rules and address technical discrepancies from there.
The FS cars that come with CNC'd heads certainly need to be held to a more finite set of standards than 60's and 70's products. I have a story about C/SM and Chev 461 heads that's too long to relate here.

Here is a real simple scenario that could play out and potentially cover a lot of cars in a reasonable amount of time. After the last qualifying run on Wednesday park all the cars in an area near the teardown barn and ask everyone to remove their carburetors or throttle bodies. The tech officials could take one of the readily available high-quality video probes and take a look down the intake manifolds for anything that may be suspicious. Depending on the time available, the suspicious intakes could be pulled then and inspected or sealed and those cars will get an automatic invitation to teardown. It’s clear there is a new Sheriff and Deputy in town!

Tough to put the genie back in the bottle..... -Al

On the older cars they look at the "texture" of the cast,and run a finger in the runner.If it don't look or feel right your gone.Red Anderson(div.4) had one of those magic fingers. gsa612

Be thankful they're taking this a bit more seriously. They could solve this problem with a stroke of their pen. Imagine a rule book entry like "stock intake and exhaust valve diameter required; any other head modification allowed" and "any intake manifold or modification allowed as long as the material matches the orginal and it fits the stock carb".


I think more races are won and lost on the drag strip than in the teardown barn.

Wow you really don’t understand class racing...

From what I have been told NHRA is trying to bring things back under control based on a incident that happened in the recent past. Wesley will lead in this endeavor.
