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=2735Dougs: 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=skuTTIs: -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=13911Hooker 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.

Eddy heads?
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.

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...
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.

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.
