It is killing me too. If Steve Wann has something to do with it, you know it is wicked fast. Ie: A/SA record. The Duster used to be Stevè's car.

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

No BS or assuming at all, that's what happened in the real world. The test was as accurate as we could make it, and just didn't see anything other than some weight off the nose.

Of course, with you running in the same class as the 340 combo, I understand your concern over any perceived advantage it, or any other E/SA combo may have over yours.

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

Seems to me that's where the credit belongs.

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

if you bolted a stock cast iron intake on that duster it would run exactly the same as the ld 340 . we tried all of that crap 20 plus years ago you would be surprised how little change intake have , they don't turn enough rpm to make a difference. maybe just maybe they spent the time to make the carburetor and fuel system converter gearing shift points etc..... work properly , only benefit I see is 20# in the trunk.

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

Amen to that!

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

If you don't think they turn a bunch more rpm than they did 20 years you must of been sleeping this whole time. It's amazing what tons of spring pressure, roller rockers, and new cam lobe designs will do.

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

I've followed this thread for a little while, and I am not that smart, so help me out here.

Someone lobbied NHRA to allow an aftermarket intake manifold in stock eliminator. Correct?

Yet this manifold has ZERO performance benefit?

See you at the races,

I ran out of popcorn 15 pages ago.

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

Doesn't matter if it is a performance gain or not, it should not have been allowed.

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

I'm pretty sure aluminum cuts, welds, and grinds easier too.

I know. That's not worth anything either.

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

I haven't posted in years, probably will be years again until next time.
I just couldn't resist this time.
I also think the intake shouldn't been allowed, like everything else thats been going on in the past,but why didn't we start this renegade 10-15 years ago????
I can understand the pain of the Hills who has got their 350 downrated quite a bit only now to get molested by a mopar with a totally bogus intake.(if they use it)

I dont remember if the Fords were the first out but I do remember police Cams,Chevy Rods, Shelbys with single carb,Dual carb,big cam,small cam,high comp,low comp or whatever, 390s with oil pans touching the ground and then if you open the the hood it's "Edelbrock everything" + a Holley I am not sure about.
I remember from back in the day that I was thinking: the Ford Guys must have someone in the committee who really likes them alot.
Not to speak about the 396 aluminum head engine that showed up in the 90's,is there a single oem part on that engine now?
Is there really a lack of intakes and Carbs for the B.B. Chevys? Is the aftermarket intake worth a total of 0.0 and thats why it is on every car?
Still no mention of all above, but this Mopar intake really got people concerned.
This thread to me seem to be about all that injustice that happened in the past but happens to single out this one instance.

Flame Away , I am going into retirement again!

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

Aluminum rods and titanium valves will be here soon. See there will be a steel shortage so we'll have to go to aluminum and titanium. Oh and there will be no advantage at all using them 😉

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

I agree with you about the after market parts. As a friend of mine said about the 390 Fords, they are school bus motors. One thing you are not right about is the "Hills" getting their 350 motor down rated . I only built one of the 70 LT 1's after it was factored in 2002 and I had nothing to do with getting it defactored. No one in their right mind would run one at 360 hp. I always ran the 71-72 combination which was rated at 315 hp and factory rated at 330 or 255 depending on which year you claimed. I have never written a letter trying to get anything defactored.

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

Perhaps mentioned previously, if so I apologize, but maybe it was an "enhancement" to the Manufacturer? (of the part)

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

x2

BTW The track where the d/sa record was set is a very very fast track.I was the next car down the track and was -1 plus under.He did everything right including,the combo, the day,the track, the weather and traction was the best I've seen any where.

you should be happy for them.

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

This run should receive automatic HP How much is it going to get and when??

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

I am happy for them. I congratulated Jerry. It was a hell of a run!

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

At a National open, none at all

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

Hmmm..no comments yet


Kinda wondering about the LD4B manifold now on the 273 4bbls.
Same basic manifold as the one in question here.
No gain on that one either?

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

How many of the single four barrel NASCAR version Hemi cars run the OEM intake?

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

I can't comment on ET, but my preliminary flow testing resulted in a loss of several CFM with the LD4B on over the bare head. The ports in the manifold were wider and taller than the ports in my 920 casting head. I suppose there are methods to fix that. I just bought some 302 castings from Terry Dye so maybe they have bigger ports that fit better? They are still in plastic bags from my trip to Detroit.

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

If it has a Factory number on it, it should be allowed!

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

This is BS. How come they only want to produce aftermarket intakes for the 273's 4 bbls. Us 273, 2 bbl guys get the shaft again. They don't give us the Chevy, Ford, Mopar bonus packages. No, they just pencil in some whole combo instead. Total BS.

OK, continue with your one component objections. I don't want to hear how some of you work your tails off for some bogus part to hurt your class. You need to deal with NHRA to really get this crap straightened out.

U/SA with the stroke of a pen

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

Ron, these intakes have not been made since the 60's.

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

The single 4 barrel NASCAR 426 Hemi is allowed to use the 426 crate motor dual plane intake with a 4781 Holley.

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

I understand David, just poking fun at the 4 bbl crowd. NHRA let this get out of control, if they didn't we would not be having this conversation. But hey, it is their playground.

Ron Ortiz
U/SA is there anybody out there

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

Since Stock and Super Stock is so boring to the fans, NHRA is trying to make some excitement. They're trying to sell tickets, not caring what the racer wants or likes. Like one said, it's their game, do they really care if you show up to race? Just the peasants mumbling and grumbling again. Sounds like when they got rid of modified and gas to make the comp class.

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

I should of said " we all should be happy for them" sorry for the " you "

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

AMC Edelbrock R4B (same as LD4B except manifold base) has an AMC p/n
It is also in SAE documentation
Approved as superseded part by NHRA on request of Chrysler then taken away 6 months later by NHRA.
So how much longer will this one be allowed to run its course?
Exact same sequence of events and documentation occurred for approval.

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

"]AMC Edelbrock R4B (same as LD4B except manifold base) has an AMC p/n"


some do, some don't
mine does

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

No Alum.Heads or Manifolds on our 340s..... we are not willing to spend the money anyway on what the heads cost let
alone a complete engine.

We still won class out of a pretty stout field last time it was out West (April) and also the majority of our "Heads Up" races
over the last few years.

The engine builder and my very good friend we often have used over the years said............$10,000+ for a set and $40,000 plus
for a complete record setting D/SA 340 that is 1.5 + under and THAT is to a good friend.

I have been racing 340s since New AND we both will go 1.10 under in good Air IF we have to.......................But Nearly 1,6 under is IMPOSSIBLE for us no matter how hard we work (Believe me we Do!)
on our decent sized budget.


$10,000 is more than I paid for either of the Demons turnkey OR the Wagon turnkey.......Never mind $40,000+

We probably should go on back soon to just Bracket Racing and save the money for my grand kids to use.

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

Actually, the R4B is the same as the LD340..the subject of this thread, except for the port match.
There's a lesson here for AMC racers:
Ask for one piece at a time.. Manifold, (Chrysler, Ford) Cam , (Ford) , Carb, (Ford)

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

I get the impression the manufacturers either have never read the rule book or really don't care what it says. A big name racer asks for something to get approved, their buddy at the manufacturer goes for it, NHRA buckles.

Jim Mantle V/SA 6632

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

But the manufacturer doesn't make the intake manifolds any more that are being discussed! Heads are a different story.


The biggest side benefit of approved aftermarket parts is that it helps keep the aftermarket industry going. However, there is nowhere near as much logic and consistency in approved/superseded parts as there should be.

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

It appears that the 1970 combo has become the choice du jour, is the LD340 the reason per chance?

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

Just remember the old saying " what goes around comes around ".

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

Pontiac put their part number on this for the '62, and '63 cars. Guess I can use it too? (and please bone heads...accept the sarcasm)

That intake doesn't look that much different than the bathtub model, give or take an inch or three. John Kissel

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

Did you submit the M/T Poncho Hemi heads to NHRA as well?
