Another 383 only left hand exhaust manifold being advertised as also for a 440. Doesn't anyone check more than one internet source or look at a parts book anymore?

 

[Fury440]

Mymopar shows it as 383/440 70-71 but what it doesn't say is the exhaust pipe will be different because the 440 is taller. Doesn't make any difference if the exhaust will be fabricated to fit.

 

[FURYGT]

Bill, Mymopar is Wrong. We went through this last week. #3418352 is the casting number for a 70 - 71 C Body left 440 HP manifold.

Which is correct HP manifold for a '70 New Yorker?

Sorry Bill, I used the 216 on my Fury, but I see in another listing your 352 shown for HP and 6pak. Got to love the internet, every question has multiple answers and maybe, if you are lucky, one will be right! LOL Here is the listing I found in my files.

1970 383 2bbl
Right - Part # 2899954, Casting 2899970 - B,C,E bodies
Left - Part # 2951860, Casting 2951861 - C body only

1970 383 4bbl
Right - Part # 2899968, Casting 2899879 - B,C,E bodies
Left - Part # 2951217, Casting 2951216 - C body only

1970 440 4bbl
Right - Part # 2899954, Casting 2899970 - B,C,E bodies
Left - Part # 2951860, Casting 2951861 - C body only

1970 440 HP and 440 6-pack
Right - Part # 2899968, Casting 2899879 - B,C,E bodies
Left - Part # 3418352, Casting 3418351 - C body only

Note that all will fit on C body cars, the only differences are either height differences (383 vs 440 block heights) and or the clocking of the exhaust pipe flange.

 

[LocuMob]

What years were HP manifolds available in C body cars? Were they available before 1970?

 

[polara71]

yes

 

[LocuMob]

yes

So, would it be incorrect to throw a set on my '66 500 with a 383?

 

[polara71]

yes

 

[LocuMob]

yes

As I was just discovering. I have the correct manifolds for my application. I wouldn't have cared five years ago.

I fully understand the statement and your thought process . Not sure what changes within us but it seems to change in most.

Not being argumentative here.. just pointing out a couple of things. Apparently, it depends on the source as to which manifold is correct for this application, C body 440 hp. I have a 1971 police package with U code 440. The guy I got it from was adamant that the car still had the factory exhaust system, except for one tailpipe.. that was scavenged from another police car. He told me the mufflers were correct, and had been recently replaced. I never really questioned this information. They are definitely hp style, upswept manifolds, with a stove on the drivers side.. connected by a flexible tube to the air cleaner. Today, I actually checked the part numbers. On the drivers side, it has casting number 2951216, and the passenger side is 2899879. Drivers side has a flat face flange, not sure of the passenger side. I assume they can be for either 2 1/2” or 2 1/4” pipes. The passenger side manifold has the heat riser in it.. still going tink tink tink…. That familiar Mopar noise. The only thing I noticed that doesn’t look quite right is the clearance between the drivers side manifold bolts and the steering coupling.. it’s pretty close. Now.. I have looked for the 3418351 manifold.. not many out there, and what’s available is either very expensive or damaged.. missing stove, broken bolts, etc. Some of the places I have looked say both manifolds are correct for the c body hp application. The difference in the deck height between a 383 vs 440 block is minimal, like less then 0.75”. I don’t know how much it really matters.. but I don’t see changing mine. Just throwing in my 2 cents

The Galen parts book says 383-4 as well.

I get it. Like I said, it seems to depend on the source. Some put 3 together, that I guess interchange? That is 3418351, 2951216, and 2863409. I’ve seen pictures, and you have too. I haven’t specifically looked up 2863409 yet. I don’t know what the application is.. maybe you do? What I can tell you, though.. is I got my car in 1998.. and I know what I replaced. I got it from Glenn Hilpert. He had 2 of them. Mine was better cosmetically, his was better mechanically. He is a retired CHP officer. He actually spent time driving cars like this. I believe what he told me. I think somewhere on this site is his 1971 Polara. So.. is it possible that the exhaust in this car was changed out with a system from a car with a 383.. I suppose so, but I doubt it.

Just felt someone should point out that you fella's are debating a 3 year old CL add... part is gone.. enjoy

Well, no.. we aren’t debating the Craigslist add.. we are debating the casting numbers and application. With all due respect.. this topic has been ongoing for several years. Anyone trying to find the correct parts for their car cares about stuff like this. I know it’s an old post.. but still relevant. Galen is one source.. many other sources show both part numbers can be used. The blocks and heads didn’t change from 1969 to 1970.. the 1969 casting number fits both 383 and 440 engines, casting number 2863409. For some reason, Chrysler decided there should be 2 different manifolds for the drivers side in 1970.. 3418351 and 2951216 in the same car. I posted a picture of the 3418351 to show the difference between the two.. which is what FuryGT was talking about. His reference material shows the 2951216 manifold for the 383 application, and the 3418351 for the 440 application in the same car. As far as I know, both 383 and 440 heads are interchangeable. So.. who knows why they did it..

Enough of a difference that I needed to extend my head pipes when I went from a 383 to a 440. It matters, hence a different manifold for the raised height of the RB engine.

Did you post it here? Only the pictures from the CL ad appear in this thread.

When I was getting my 71 Polara Patrol car back on the road, I ran into that. The car was a HP 383 and I swapped to a 440. I have the Galen white books and saw that there were 2 different casting numbers between the 383 and the 440. I just assumed the 383 manifold would work on the 440. I had ordered a TTI exhaust with the 383 casting number but told them I was using a 440. Putting the pipes on starting from the rear. I get to the left headpipe, No way was it going to fit. I called TTI and asked what was wrong. They sent me the correct headpipe for the 440 manifold and he explained the difference, even though I gave him the 383 casting number. If you were having pipes bent at a muffler shop you might be able to get the wrong manifold to fit. I just remember the 383 manifold on the 440 ran almost squarely into the steering shaft. So I Googled the 2 manifolds and could clearly see the difference between the 2. So, I sat there-what to do? I called Murray Park, he had one for a fair price. I installed it and the TTI headpipe bolted right up. Kudo's to TTI, their customer service is tops in my book.

Whereas that may be true, the factory didn't use the same head pipe on the 383 and 440 and the rise was probably different to make up the difference.

Different flange faces is the major difference?
