Billy, Please report to Virginia for your counseling session. Mom has you room ready.

If someone with a 340 combination would like to use an LD340 intake manifold, they can: run Super Stock.

The benefit of the doubt is yours Sir.

Did the LD340 come on the 340's in question? Answer: No.

I think this tells the whole story.

I'm surprised no one seems to want to JUST STOP it, NHRA.

Are there a few more personal agendas that need to be slipped through first?

What's the latest "safety" item needed?

Re: Important if you run D-H/S or SA
 

Jim, if someone went through the blueprint specs, quite a few cars do not have the manifold (and plenty other stuff0 that came on the cars. Good example is a 70 350/325 that is in the Camaro that year has a manifold allowed in 2012. Those also run D & E and maybe more. I'm sure there a good explanation for that one. Anyone know? Just look in the blueprint specs and look for the yellow highlight on that combo.

Jeff - The manifold you note for the 1971 Z28 is a Chevrolet produced part to replace the original 594 aluminum intake. The manifold has some slight modifications for throttle linkage bosses and alternator mounting so it could be used on the ZZ3 and ZZ4 crate motors. It's not an apples to apples comparison to the Edelbrock LD340 vs stock cast iron manifold. That's not to say that there are not parts in the tech guides that aren't correct, but it's one thing when the factory proclaims "improved" replacement parts (i.e. Chevy's replacement 401 BB aluminum heads, MoPar's many 559 heads for the Hemi, etc.etc.) and yet a totally different issue when a 50 year old aftermarket part is suddenly made legal that was never proclaimed by the factory as a replacement.

Hi Jeff,

I get it, I really do get it, and I mean that I really really do get it.....

So why does NHRA continue to make the mistakes of the past better by continuing to make mistakes in the present??????

I don't have a clue and obviously neither does the NHRA...

PS:
I really do get it

Mr Jeff, The point is ..we know all this.The question is "What do we do about it in 2017 ?"


Suggestion # 1,
Roll everything back to 1980 rules.
(This one won't fly, due to financial loss.)
I will help, if that's the concensus.

#2, Let it fly, until it morphs completely into Bracket II .
(There's probably a few who want the delay boxes too, but we'll go with II for now)

#3, JUST STOP, NOW. NO changes for 5 years.
This would include..No new HP combos before Indy for the FX cars.

Anyone who would like to turn this into an official C/R poll, be my guest.

We know you really get it,but Mr Jeff is the one that really does not get it.LOL
