Here a manifold header shootout on a stock 4bbl magnum, there's another out there somewhere that has magnums and there basically on par with 340 ones, they found the best combination to be one 340 and one magnum manifold, I forget which ones but was only better by a hp or two. As for 273...

They are not that hard to find if you have about $600-900 in your wallet. They even make them new now. If you don’t want to the spend that much, the 72-74 a body 340 360 manifolds are a lot cheaper. That is what I have on my 69 Cuda.

...experience, I replaced the stock manifolds on my old otherwise stock 73 Duster 340 with cheap BlackJack headers, and replaced the 68-70 340 manifolds on the mildly modified 340 in my 65 Barracuda and the mildly modified 360 in my 67 Barracuda coupe with TTI. In all cases, the power...

The 72-73 340 manifolds will work just fine, but make sure the drivers side is for an A body. Passenger side is the same between A, B and E bodies, but the drivers side is specific for A body cars. The only difference between a 68-70 drivers side 340 HP manifold and a 72-76 340/360 drivers side...

Thanks, brother. I almost have all the parts I need to really start my restoration! Maybe in 3 years I'll have it on the road. :)

Yep stock magnum heads with 340 manifolds had that combo for years then swapped to headers still using that same part number gasket with headers now. Remflex Inc. 6004 Remflex Exhaust Header Gasket Sets | Summit Racing

It made 341.3 and climbing still @5700 with manifolds with the chit 72 manifolds

Never understood why folks look down on a 318. If a 302 ford and 327 Chevy can make power why not a 318? Yes it has smaller heads (in most situations) Low compression (unless you got an early one) and probably has a 2 barrel intake and shitty exhaust manifolds (performance wise) but rebuild it...

Probably so. 73 340's ran pretty good but they were pretty anemic compared to the 68 and newer ones. 73 was the last year for the 340 and everything got a 318 or 360 from there. The 360's were built like the 340's of that era. Heads, cams, manifolds, etc were interchangeable. The 360 would...

I used these manifolds on my 69 360 barracuda. They work great. I have power steering and brakes. I used stock exhaust pipes I ordered from Waldron. You just have to make sure you order the head pipes for manifolds you are using if you go that route. The 72 to 74 manifolds are the ones I used...

I have seen threads on this forum with this discussed before and I believe the EQ heads have extra casting material around the ports to allow 340 manifolds to seal. The magnum heads from Hughs may also have the extra material.

Does anyone know if these are being reproduced? Would like to go this route instead of headers. Thanks

Selling 1972 340 engine with 340 hp manifolds and Unsilenced air cleaner. This engine has been rebuilt and has been in storage for several years. It has fresh oil in it currently. I turn the engine manually to keep it lubed and free. Asking $4500 or best offer. Also have a rebuilt 833 A OD 4...

Nice set of 340/360 exhaust manifolds. Looks like these fit A-body with the passenger side also fitting B & E body. They are cast numbers 3418623 & 3614368. The passenger side has never been drilled for a heat riser so you don’t have to deal with it rattling around or rebuilding it or just...

In a ?

I have very little in it, $150 to fix would be worth it to me

Will Sanderson shorty headers for 340 1970 dart swinger with power steering? Friend found a set cheaper than manifolds was was thinking of putting them on her car. Not race car, street car cruiser.

Worth it is an opinion, depends on if you plan on doing more mods in the future. Why not use the 74-76 360 A-Body manifolds? They are much cheaper and flow pretty well... [FOR SALE] - 1972-74 OEM 340/360 HP exhaust manifold set

I have the best of both worlds. My '69 Dart which has Doug's headers on a 340, has a high torque mini starter. It works fantastic and clears the headers by quite a bit. Definitely the way to go in this case. My '69 Valiant which is a 318 with stock manifolds has a high torque regular Chrysler...

Damn, was hoping you found a solution with the headers. I have Dougs installed and am about to attempt to install the column in a couple weeks. Glad you found an overall solution for yourself. Sometimes it's best just to do what it takes to get it back on the road.

Here's one site that has reproductions. No heat riser that I can see though. 1968-71 340 Exhaust Manifolds Duster Dart Plymouth Cuda TA AAR Challenger GTS 70 – Mopar Hoods Here's the option I chose. Worked out great for me. https://www.ttiexhaust.com/TTi34025.htm#pricing

I just used 308 style heads on a 318, tapped and blocked the air ports and installed 68-70 340 manifolds with no sealing issues whatsoever.

You also have to grind on Eddie 318-340-360 RPM aluminium heads and manifolds. I did a little on each, so as not to have to grind to much in heads or manifolds. It is due to the fact that they used the same casting as late heads where there is a threaded port below the manifold for smog cheap...

...depends on engine combo. If you go with TTI exhaust with manifolds then decide later want headers you can pull head pipes out of H pipe and swap in shorty pipes to hook to headers. Thats what I did I used to run 340 manifolds then when orig eng got replaced with stroker eng switched to...

Showoff. lol You should hire out to detail engine bays.

A little off the original point... I have been curious for a while which if any factory 340 exhaust manifolds flow better. Or are they all pretty much the same.

...on my Barracuda. So put some on my fox body and they sounded terrible. So swapped on Dynomax Super Turbos on the fox body which turned out great. With 340 manifolds 2 1/4 outlet going into 2 1/2 TTI head pipes, I ran that combo once, something like a Dynomax Super Turbo should get rid of...

...if it was me; I would get the 340 ones, cuz later, to get your power-numbers, you will for sure need headers, and then you can sell the 340 manifolds for the same or more than what you paid for them. Whereas, selling the less popular logs, bought from a store, you will take a hit on them...

Is anyone reproducing the '68-'70 340 Exhaust Manifolds? I'm looking to buy a set for an upcoming small block build. I don't want to use headers. Thanks

So would a 1970 340 be the right application for this size? Again I have the dimensions but everything is based off application. Also I noticed that the opening in the manifold does not have any lip. It’s all flat. Is that how the stick manifolds are as well?
