I am finally getting around to doing this car. I am putting a 340 in the '65 Barracuda.

1) What is the best exhaust set-up for this car? I am sure many of you have been down this path, apprecite any help.

Info: All street, occasional daily driver for my Mrs.
The 340 is barely above stock. .030 over, heavy SP pistons, Eagle I Beams, 360 heads, LD340, Eddie 650 and I have not picked the cam yet, want to match it to the exhaust. Can go either solid or hydraulic.

These cars only came with single exhaust new, and there is no provision on the right side crossmember for exhaust. Headers? 340 hp manifolds? I currently have the 273 manifolds and '98 magnum manifolds.



2) Trans- I want to retain the stock cable shift "consolette" set up. Can I put a later model 904 tail shaft and housing on this 904? I want to get rid of the stock Detroit front joint.
I am converting the rear to an 8 3/4.

Thanks again for any help.

You can use 340 HP manifolds,but the drivers side will hit the steering column housing.You might be able to modify the housing to work,but I've never done it myself.TTI is making headers for early A-bodies now,but I haven't heard whether they got an issue with the starter worked out or not A company called Imperial Services makes adapter cables so you can use your factory shifter with a later 904.A 727 will fit if you beat the pinch weld in the transmission tunnel flat with a hammer.A later 904 or 999 will fit better and work just fine if you build it to withstand more HP.On the crossmember,you can modify the passenger side so a pipe will fit that side.If I remember right,the bolt in part is all that needs modification.The welded in torsion bar crossmember already has a dip in it on that side.Good luck

I can help answer #1, but I'll warn you - there is a lot of info on this subject. First thing would be to find out if you have power steering since some option will not work with power steering.

First let me list the choices and price points:
340 manifolds (~$350 used)
Spitfire Headers / Layson copy-cat product ($225/$500)
Doug's ($620)
TTI's ($700+ - Can't seem to find the exact price right now)
Hooker fenderwell ($500+)

Now I will try and get info on each option-

340 Manifolds:
-Can't use with power steering and have heard others needing to make minor mods to the steering shaft. I know one guy who did some welding and fabrication work to get them to work with power steering, but that would be some major mods - IMO.
-Will last the longest, headers eventually go bad and you can always re-sell them later down the road.

Spitfires:
-There will be a ton of info on these if you seach. In a nut shell, people have had problems getting Harold, the one man shop, to deliver in a timely manner. However, people have been getting their orders and as for headers, they are the cheapest option.
-Again, no power steering
-Info and pictures can be found on this link:
http://www.forabodiesonly.com/mopar/showthread.php?t=2735

Dougs:
Been around a long time and were the original ones used for hi-po 273 application back in the day. Summit has application information on what you can and can't use. They are smaller than the TTIs, but for your engine combo, would be plenty big.
http://store.summitracing.com/partdetail...mp;autoview=sku

TTIs:
-Newest ones on the market
-Have to buy a special small starter ($240)
-They have a full exhuast to go with it
More info here:
http://www.forabodiesonly.com/mopar/showthread.php?t=13911

Hooker Fenderwell:
-You have to cut up your car - that's about all I'm gonna say.

If you have the money, both the TTIs or the Doug's would be a good option. If you are on a budget and/or aren't worried that much about loosing a few HP, I'm sure you would be happy in the end with either 340 manifolds or Spitfires.

HOpe this helps.

Thanks very much for the information, I have a couple of the later 904s. I try and find Imperial Services. It looked to me like I would need to cut a section and weeken the crossmember, I will check again.

Awesome information, thanks! No power steering, I am sure I will hear about that from her. If the 340 manifolds will work, that would be my preference. That is what I put on my 68 with TTI 2 1/2 on back, very pricy but the nicest stuff I have ever seen.
Amazing Doug Headers are so high, but they were the choice back in the 60s. I appreciate the links very much!

On the Headers I use Harold Johnson (Splitfire) $225 Deliver to your Door (COD).I just put set on my 65 Barracuda last week..No problem with the started use the small one..Did hit the steering..What I did is cut the outer housing off about 2" and reinstall the Plasted Bushing..Where it goes on the Steering Box I did away with the Factory Hookup and order a 36 spline Coupler and welded it to my steering shaft and the spline in went right on the Steering Box...That way you only have the 3/4" steering shaft going through there and it want hit the headers.

On my manual steering 65 Barracuda, I fixed the steering clearance problem by running a power steering column (shorter shaft) with a firm feel adaptor between the steering box and the coupler. This moved the coupler back out of the way.

After doing this, a 340 driver's side manifold clears everything, but you'll have to run the exhaust pipe between the torsion bar and the frame. There's one place where it will fit OK.

On the passenger side, a center dump 71-up A body 340/360 manifold fits well, but only has a 2" outlet. The earlier rear dump hi-po 340 manifold may or may not clear the inner fender where it juts out around the UCA bushing.

I never bothered modifying my trans crossmember, just ran the passenger side pipe under it as is. You only need to drop the pipe an inch or so to clear, which is no big deal, I don't think. From there on back, the chassis is identical to later 108" wb A bodies (i.e., 67-9 Barracudas and Dusters/Demons) except for the side-to-side gas tank strap (same as 67, different than 68-up's front-to-rear dual straps) and whatever exhaust will fit on them will fit on a 65 Barracuda. I have 67-up A body Walker replacement tail pipes (NLA) and factory 69 Barracuda tips on mine.

The manifolds won't make as much power as headers, but mine IS faster now than it was when it had fenderwell headers a couple of decades ago.

Thanks wupracing and 413 coronet, sounds like I should count on modifying the steering shaft no matter which way I go.
Nice job and beautiful car 413 coronet. Eddy heads?

eddy heads wont work with the spitfires...

and I didnt have to modify my steering column for the 340 manifolds, i had to grind about 1/8th inch around the manifold, but left the steering alone...

i had column shift (66) so i had to mess with that for the spitfires... but they are the best abng for the buck.

they made a noticable difference in my car over the 340 manifolds...

Yes. The inside part of the driver's side manifold outlet hits an Eddy head and if you grind the head enough to clear the manifold you are supposed to hit water. I didn't know that, so just ground on the head till it cleared and so far no leaks.

Yeah, the stock manual steering coupler almost clears; mine only hit when the motor torqued over. Originally I just ground the corners off the coupler housing and that was sufficient. Changed to the power steering column later because I didn't like running with no cap on the coupler top - even though I had for years with no negative consequences. I already had a PS column, so that didn't cost anything, but the adaptor is around $100 these days so you may want to go another route.

1) i would find a st of spitfire headders.. they will give good performance for what your doing and not cost a tom of money, hooker and headmans are fenderwell, the tti for the early a-body cost about $1000 i think it is and has starter fitment issues from what i hear, the dougs fit good but also cost up around $1000....

i heard that harold is making the spitfires again for like $250 or so. just make sure you order them COD... call harold johnson @ 479-650-9989 there was a guy at forabodiesonly.com that recently bought and recieved a set....


2) i would stick a newer 904 in it to open he doors to off the shelf convertors and get rid of that joint your talking about...... it you still want to run the cable shift contact the guys at http://www.imperialservices.net/ they convert your stuff to work with a newer style trans....

Wow, great info, Spitfire it is. I have a couple of late 904s already and 3 of the old ones. Are you saying the converters are different? I was not aware of that.

someone will chime in with the year, but lder ones have a smaller diam input shaft, which no one makes a good converter for.

yes... the older ones are limited on what you can get for them and more expensive.. the newer 904 has alot of convertors avalible for them and cheaper too... i think they changed in the later 60's not sure on the year though...

I think the price for Doug's has gone down since they were bought by Pertronix. Summit lists the non-coated sets at $620 and the coated sets at $780. Still pricey, although not too bad considering how much we spend on other things for our cars.

I have a later style 67+ A body manifold on the driver's side of a 66 A body with no modifications to the steering shaft (manual steering). I had to grind on the collector flange of the manifold to clear the steering, quite a bit, but it fits with no interference. What I ground away was just extra casting material. I am using a magnum truck manifold on the pass. side. I have magnum heads anyway on an LA, but the magnum manifold will fit LA heads as well.

I am not sure about the best exhaust, but the easiest and least expensive for a daily driver is to use the stock 273 manifolds. Check this artical out regarding flow, someone sent it to me when I was asking a similar question. http://www.moparmusclemagazine.com/techarticles/155_0307_mopar_crate_engine_exhaust/
We put a 360 in our 65 barracuda and used the stock manifolds. We stepped the outlets up to 2" then to 2 1/4" pipe and snaked the passenger side around the trans pan so both pipes come together (side by side)at the tranny cross member on the driver's side. It is really clean see attached.
If I would have considered it earlier in the build, I would have modified the crossmember but I am happy with the way we did it.
In order to get larger pipes in I went ahead and converted the kickdown to lokar. That really simplified the system and gave me more room.

So the mounting tabs are different on a 273 block than the 340 block? I had not even considered that problem.

I am not sure about the best exhaust, but the easiest and least expensive for a daily driver is to use the stock 273 manifolds. Check this artical out regarding flow, someone sent it to me when I was asking a similar question. http://www.moparmusclemagazine.com/techarticles/155_0307_mopar_crate_engine_exhaust/
We put a 360 in our 65 barracuda and used the stock manifolds. We stepped the outlets up to 2" then to 2 1/4" pipe and snaked the passenger side around the trans pan so both pipes come together (side by side)at the tranny cross member on the driver's side. It is really clean see attached.
If I would have considered it earlier in the build, I would have modified the crossmember but I am happy with the way we did it.
In order to get larger pipes in I went ahead and converted the kickdown to lokar. That really simplified the system and gave me more room.




Very informative, I am not going to worry about 11 hp at over 4 grand on this project. It may be worthwhile just to use the 273 manifolds and do a similar exhaust set up to yours. The lokar was already in the plans. Thanks very much!

the 273 manifolds will probably choke a 340.. they are really small..

You are certainly correct about the smallness, and that is the reason I started this thread. But if I read the article linked correctly, it is only a little over 10 hp loss. Maybe I am misreading the manifolds they used?

69 A body 318 manifolds, is there much difference between them and the 273 manifolds?

After I read that article I measured a set of 318 A Body manifolds and the outlets on the ones I have are the same. That was what made my mind up.
The 273 manifolds will not "choke" your 340. Refer to the artical, I believe that the mule engine for those tests was a 300 HP 360.
My 360 does just fine. It would be nice to run headers and 2 1/2 pipes but on our car it is not worth the price or headache to me.
There is very little room to work with on the early A Bodies anyway.

well i can tell you one thing... i had 340 manifolds and they choked my 360 in there, compared to spitfires, and people say they dont flow...

trust me with that stupid 90º turn, and small ports on the 273 manifolds your loosing lot more then 10 hp.

i dont have to dyno a motor to tell you that....

you guys running the 273 manifolds on a 360 or 340 do what you want... bit it definatley is gonna choke it,,, yea the car may be fast enough for you but it sure isn't gonna be anywhere near what it could... look at that 273 manifold... its small and makes a hard turn.. that thing is restrictive... i have had a 360 in a 64 valiant with those crappy manifolds so i am not just talking out my rear here...

and heck you wouldn't believe the difference in djv's car going from a 340 manifold (wich is way bigger and didn't have that bend like the 273 manifold) to the spitfires was incredible.. night and day...



on a side note.. you may have to grind a little on the head i think it was for the manifold to sit flat on a 340/360. it was years ago so i don't exactly remember what it was hitting....

heck if i believed everything i read i would have never put a 440 in my 64 valiant... i saw in a couple magazines back then that said it wouldn't fit.. and you know how many oldheads said it would never fit... if you ask me it was easier to work on with the 440 then when it had the 360 in it....

take 2 tranny crossmembers & cut & weld them together so your exhaust pipe will tuck up nicely on each side. RR

If you look back at my first post, I said "I don't know about the best" and went on to say what I did and why. Are there better systems? of course there are. Could you build more horse power with headers and bigger pipe? yes.
I stand corrected in that there is a lot of room if you cut the fender wells.
The bottom line is that the 273 manifolds are an option and it is all personal preference and what an individual wants out of a car. I am talking ease of install, cheap, and clean. Once again, our 360 runs out just fine for a street car.
Believe what you read or not it is up to you.

you don't need to get wound up... if you read my post i said do what you want.....

but not the best is an understatement... atleast go with a 340 manifold.. but then again now your getting to spitfire prices...


i would consider spitfires maybe not the best but work pretty well and fit prett good...


the 273 manifolds are useless on anything over a 318....


have you compared the 273 gasket to the port on the 340/360 heads?? its crazy how small it is compared to the port...

like i said.. do what you want... i just can't see going through the trouble of building a 340 and sticking it in and letting it exhaust through those tiny things.. especially when ther is a relativley cheap solution....

you can read this article http://www.compcams.com/Community/Articles/Details.asp?ID=-738676943 and it says the headders added 15hp over the best flowing 340 manifolds made. (the early ones..) now look at those early 340 manifolds and then look at the 273 early a-body manifold and tell me there isn't night and day between them....

That is good idea, the crossmember that has the torsion bars attached to it seems like it would be the biggest problem. That is why I like how moparmedic ran his over together on the drivers side. Pretty slick!

Looks like the TTI:s wouldn't work with power steering? The Doug's seem to fit with power steering too...anyone have any experience with that? The TTI website didn't have the early A-body parts listed yet.

Here's a budget solution that hasn't been mentioned, Durango/Dakota manifolds;

Are Spitfires really THAT much cheaper. Lets do some math.

Spitfires are $225 (uncoated)
I found Dougs for $550 (uncoated)

So yes they are $275 different. However, the thing to think about is how much extra it is going to cost to have an exhuast shop create exhuast for the non-full legnth headers (they have to snake exhuast up through the engine bay) compared to the simplistic ease of doing exhuat for full-legnth headers. Although I don't have exact info, my guess that it would be at least 100-150 difference.

So Doug's could potentially only be $125-175 difference. Just food for thought.

I really like this idea, I have a set of these on the shelf that I was ignorant enough to take off of my 98 Durango. I put the Ede Stainless Headers on it, waste of time and money.

Even the MP mini-starter doesn't work with the TTI's, you need the powermaster mini starter for $240 to make them fit.

This site says yes on the PS, but I would always do research and talk to the folks who produce the product. From what I hear, calling and talking to TTI is usually really helpful.

OK, thanks. I will call before I order anything. I was just curious at this point since they have the complete exhaust available. That would make things easier...

thats $325 to start right off the bat... i'm not sure what the exhaust cost around your way but the guy i take my car to sure as heck isn't charging $150 to do that little bit of extra pipe... lucky if he charged $75...

2 things....

spitfires fit in an oven... you can hi-temp powder coat them at home -




i was charged way under 100 bux to have my exhaust fit to my spitfires, and have cutouts added...... ( went from manifolds, remember)

I would sure like to see more pictures of your set up. Sounds and looks like you got a great deal.

I just received them today, they look great. Harold made numerous contacts with me to follow up and let me know when they were shipping. Very fast and happy with the service. For $225 they look like a bargain to me right now, thanks for the info everyone.

Thanks to everyone for their help, a little over 800 hours later, I delivered it back to Dad and he was very happy!

That looks great. Does it run nice and hard? that was a great Street Racer combo back in the 70's.

Thanks! It runs and drives very nice. The 3;23 posi unit that I paid $425 for at the Larry Roesch swap meet, turned out to be junk. So I ended up throwing a 2:76 one legger in it for now, until I get the 742 rebuilt. The 2:76 kind of takes some of the fun out of the 340 though, but it still runs strong. I will be putting the 3:23 in real soon now.
I had forgotten how nice one of these cars handles when everything is new.

if you are going to the trouble of a rebuilt third member make it a 3.55



The 3.23 in my Formula S is kinda tame too!!! IMHO

I would agree, but I am up to over $800 in the third member without spending another $180 on a 3:55 ring and pinion. I have a new 3:23, NOS Mopar set on the shelf. What would you do?

I would put the 3.23 in. i can do 150 on the power tour. passed a lot of brand Xs. I can do 13.97 in the 1/4. still get 18-20 mpg if i could stay out of those big qjet back brls. i used a later 904 with the low 1st gear. yes lock up t/c.
made my own mounts out of stock truck units and used the hp 340 ex manifolds. great street/cruze car.

Pretty car, beautiful! I ended up modifying my own mounts, some guy selling them on Ebay had a drawing on his auction.
I agree on the 3:23 in my case, since I am so upside down already on the deal. The spitfire headers worked out great.

Yes it wasn't hard to make the mounts. i used the stock steel brackets that came with the motor (it came out of a van) cut the amount shown out and redrilled. then used the stock 15.00 truck/van motor mounts. they are already interlocked. so no need for extra bars and chains. worked out great and cheap.
i love to use stock stuff.

Agreed, that is some of the most fun for me, when it works out. The brain trust on this board has shure been helpful on my last two projects.

i also agree with this too. I guess I'm on the fence. It is nice to cruise at 90 and have the engine not working very hard. I guess that most people usually cruise around town and seldom do 150 mph so that is where my recommendation for the 3.55 came from. The way i look at it is that you are "already into it for $800, so now at that point why stop at what may seem like the ice breaker (another $150). if you stick to the 323 you'll have a pretty expensive 3.23 that you might not be happy with. Have you considered selling the 3.23 to help offset the cost of a 3.55??

Good luck with your choices.

Steve

I just realized, I had not thanked everyone for their help on this project. The advice on here was invaluable, thanks very much!

When I took it to Dad on Fathers day, the look on his face was worth all the work.

Oops, I guess I did, but thanks again anyway.
