Important if you run D-H/S or SA

OK, lets start over. That manifold is in the book from not too long ago. It was put in by NHRA, but in checking the validity of this aforementioned manifold NHRA asked Mopar about a Technical Service Bulletin issued in 73 or 74. That bulletin would explain why it was used. NHRA asked Mopar about the manifold. and Mopar asked me as they know I have the parts books back to l960. I looked up that number and it is not there. However casting numbers are in the NHRA book and not part numbers, but from every other manifold (and other parts) in that era, the part number was usually one off (the last digit) from each other. I do not have the old TCB's, but am looking for some people who are just as old as me (maybe not as fat and stupid) that might have a collection of these Bulletins. NHRA has the number of the Bulletin, but I can't find one. Since this started Billy cited Galan Govier, a reknown Chrylser authority on what got produced by Chrysler as they allowed him to look at the old records. According to Billy that number was around, but the part number was preceeded by a "P" which indicates a Chrysler Performance part which would indicate an aftermarket part with no warranty for one thing and usually sold thru dealers and sold by Mopar Performance. A company could be a Mopar Performance dealer or any franchised dealer (which I have been since 1968). If that is the case then it is aftermarket and I have sent this to NHRA in the form of an email. And they agreed to give me a few days to see if anyone has this Bulletin. Blocks, heads, manifolds from what I remember. Now most of the time a "P' number is embossed on the part, but not all the time. I think any race block I have had did have the "P' number embossed on the block. Now if this manifold was produced as a performance item, maybe the "P" was included on the number on the thing. Someone posted a picture of the supposed manifold, but I could not enlarge it enough to see if it, the "P' was there. Maybe someone could look that picture and can see better than me. That would solve the mystery. However from 1968 on emission regulations were an issue and many times a part change was done to correct something especially in the fuel system. We have seen this many times in the years since emission controls. Probably not in this case but it has happened. So obviously I don't get it, but an explanation might be here just as the explanation was offered for the 42 year old Camaro 350. We never raced a 340 except and T/A, and it is still here in Houma with an Edlebrock manifold with the original owner. If we had raced the 4 bbl version, I would probably know. One interesting thing in this whole discussion is obviously folks have a dislike for the 340 as racers have gotten the thing to run really fast. This manifold was never in-the-book legal until 2017. Now if it has been allowed by NHRA for some time and people have been running it then it got by, then maybe we start over. (old saying 'Its not what is legal, it is what passed') And if no one has been running it, then opponents will have no relief.

in checking the validity of this aforementioned manifold NHRA asked Mopar about a Technical Service Bulletin issued in 73 or 74.

If the manifold had a legitmate right to be in the Guide based on a TSB, it should've been put in the Guide when the TSB was issued. This sounds like a case of, "Well, it's been so long now that nobody will really know, and besides, parts are just so hard to find, so they'll accept anything."

obviously folks have a dislike for the 340 as racers have gotten the thing to run really fast

"Obviously"? That assertion is unfounded. People are discussing rules. It doesn't matter who runs what combo, how fast anyone's gone, or what manufacturer's part is trying to be shoehorned into the Guide. Again, either the part is legitimate or its not. Everything else is moot.

We have an LD340 manifold in the attic. That doesn't make it legal for Stock.

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.

Hi

[Jeff Teuton]

OK. I will look again at my books and see if I can find that part number in some year. I am also looking for some old Mopar Performance catalogs that might reference it. Or I might just go drink a beer and let everyone go home.

Jeff, go to post #121 on this thread. Click on the tag. It will bring you to a 1973 parts manual (Jan.73). Go to page 2-12 of the manual. Look at Chrysler part #P3549884. You're welcome.

I will not run the aluminum manifold on
any of our cars even if legal. Our Iron stuff
is faster on our cars in testing. I will be just
as pleased if it is outlawed...... as far as we are concerned

Of course qualifying is a whole nuther game along with out running the slow guy in your class (how often is that). Let's all say together "we are just bracket racers" I guaranty nobody cried foul when their combo received a nice little gift from NHRA.

Since I have no idea who you are I have a couple of questions that might help me understand your position......

Have you ever lost a heads up race??

Does the outcome of a race matter to you??

If you have lost a heads up race what actions did you take to prevent it from happening again. That is if you do care about it happening again??

Did you find a class or eliminator to run that had no heads up racing??

Are you having fun drag racing, if you drag race??

I am just attempting to find the reason that you participate in this type of drag racing and if in fact you do participate??

Thank you,
Bob Mulry

Reality strikes Stock and SS parts supply and methods of correcting.
Allowing one aftermarket head, carb, manifold begins to get in the direction of a Spec motor doesn't it? Just killing the classes one piece at a time instead of allowing everyone to make the changes all at once and be more level field. Just my humble opinion.I know I don't own one today.

[Dave Gantz]

I wonder why Mopar sold the LD340? The consensus on here seems to be that the iron is faster.
I'm enjoying the discussion immensely.
Stock has evolved so much over the years, I wonder if anyone at NHRA even understands how it started out, and how it has evolved?
