I have a 65 Barracuda and was wondering if anyone has upgraded to exhaust manifolds that excepts 2 1/2" pipe.
 
Thanks for the info! I've had Dougs and Spitfire headers, and didn't care for either one. I guess it amounts to personal preference.

And the reason you prefer manifolds to headers is what??? Maybe noise??? Or some other reason, and what might that be, please?

I have manifolds on my car, and 2" pipes to the back bumper, with Flowmasters just ahead of the axle. The car is a cruiser, not a racer. To my ears it's just about loud enough, but still pretty sweet sounding.

My project car will be louder, anyway, with a 360 and a "fairly warm" but streetable cam and a low rear end ratio Sure Grip for acceleration giggles. Probably won't even bother with putting a radio in it, and noise won't be a factor.
 
Has anybody used the spitfire headers on a '65 with the stock column shift automatic? The shift and park cables go to a "box" on the steering column and I wonder about clearance.

340 manifolds will fit with Schumacher motor mounts. My friend has them on his 64 Barracuda. The only problem is that 340 manifolds are pricey now. Any particular reason you didn't like the Spitfires?

I've tried the Header route, and didn't care much for the fit. And would rather use the manifolds to try and keep somewhat of stock appearance. I'm using my stock 273 manifolds, on what is now a 408ci.. Just looking for better flow.

I didn't like how the spitfires outleted directly over the torsion bars. I have heard of others liking the spitfires. Just wasn't my preference.

I would think that even the 340 manifolds would be restrictive for a 408. I ran across this article some while back, before I bought my Spitfires.

Maybe it's a possible solution for you. Seems to me that manifolds factory spec for 360 c.i. would be more free flowing than those spec for even 340s, and especially for the contortions the early V-8 driver side manifold was put through.

I did see one post "somewhere" that said the Dak/Durango manis didn't work. I remember asking the poster for more specifics and got no reply.

IIRC, I was making what seemed like good progress with Harold at Spitfire on the phone, so I kept at that rather than trying Lars' approach.
 
They don't work. The dakota manifolds that is. I had a 318 in my 65 Cuda. Tried lifting the motor with shims, on one side and on both. Tried grinding on stuff....would NOT work. They hit on the steering box. I could have ground on the manifold to get them to fit, but it would have been ground all the way thru.

I ended up using a set of 75 Dodge Dart manifolds. Worked fine. I had manual steering. Those would REALLY suck on a 408, however.

Maybe grand cherokee manifolds would fit better?

Leaving me wondering who the heck this Lars person is and how he got the Dak manifolds to work. Or how he managed to spin such a believable story out of thin air. Oh, well, at least I bought the Spitfires, and didn't waste time buying manifolds that at least one person says will not work. I like better than even odds when I'm putting my money on the line. Thanks, mopar_nocar....
 
Hey, bcuda, is your car a new addition to our area? Haven't seen it around. I live about a mile away, as the crow flys, on the opposite side of the river.

Magnum manifolds do fit - they're very tight and need some grinding and ideally changing out the steering coupler but they will go in.
 
The steering coupler was where my problem was. It was going to take more grinding than there was manifold.....maybe it was my schumacher mounts. Perhaps they sit lower than the factory mounts?

BUT the 75 manifolds fit, which everyone I talked to said would not work, go figure. I even bought two different set of the manifolds based on the Lars info. Doesn't matter, I'm going back to the slant! LOL!

If there's any way to get some photos, especially of the driver's side, I (and probably others as well) would like to see them. Thanks in advance if you're able to snap a few.

As I just mentioned in a post about 340 manifolds, if you can take a couple of pics (especially of the driver's side), I and I'm sure others would like to take a gander at them. Thanks in advance if you can post any photos.
 
I've had the car 18 years. And now just starting to get it out more. Trying to iron out some minor issues. Maybe we could meet sometime.

Well I just got a set of durango manifolds, we'll see what happens. Can't be any worse than Doug's Headers. Had to shim and still had problems. All suggestions are welcome.
 
I wonder if there is a difference in the dakota/Durango manifolds by year. They would definately flow better than the 273 manifolds. If I can find some that fits decent, I don't care what it cost.
 
If you look back about a month there was a thread called 'Early a's running magnum manifolds'. I posted a couple of pictures there. I think Dakota/Durango/Ram truck/Ram van manifolds are all the same for the same model year. Apparently the earlier manifolds had a larger outlet so they may be a slightly different shape too. The grand cherokee passenger side manifold looks like it would also work - haven't seen a driver's side so don't know about that.
 
Going to try to install the late model Durango manifolds this weekend.

I'll be installing a 340 with X heads as well as an 833 4 speed replacing the 273 HiPo [that somewhere along the line someone replaced the 10.25 pistons with 8.5 slugs] into my '65 Dodge Dart original 273/904 car.
I bought a pair of Doug's Headers but now I have learned through this thread that the conversion 10.5" clutch and bellhousing (from Brewers) will not fit with the mechanical linkage and Doug's headers. Has anyone successfuly used the 340 original exhaust manifolds with the 340 10.5" bellhousing and mechanical clutch? Do I need to buy a 9.5" bellhousing and clutch and go with the Dougs, or stay with the 10.5" clutch and 340 cast iron manifold?
I can remember that I had clutch/ bent throughout arms with my original 273 HiPo Dart back in the day, but modern clutches are much superior to the original Mopars.
This whole thing is getting way more complicated than I ever imagined when I started down this path....

I don't have any here at work. I'll check to see if I have any photos of the manifolds on that car. If not, I'll have to ask my friend to take some or take some next time I'm at his house. FYI - he has manual steering on his car and had to remove the stock coupler and have a Flaming RIver coupler welded on to the steering shaft.
