Depends on the combination. The stock 340 and 360s were designed to incorporate manifolds. Very mild builds. "Just" bolting headers on and nothing else would garner very little, unless you also upped the ante with the carburetor.

Thanks Dicer. That's seems doable. Do you have a 340 with HP manifolds?

Thanks, I got tired of messing with the Offy as I was trying to get 340 built. And get to Moparfest which i missed lol. So I pulled it off the 273 and shelved the setup for now. Once 340 is installed I'm hoping to put commando pistons in 273 and then take a stab at dq again. They just look so...

I got mine used, from a member on the site for a good deal. My first thought when they were hitting after I dropped, the jack was your thread, and then I wonder if someone would want to trade for some 340 manifold?!?!? lol

My bad, that is actually a Felpro1243, shown in pic, but the pen marks shown show where the 1213 340 ports were marked. I will edit above post.

I bought same NOS dual quad thinking I could use on my 340 build(x heads)....not a chance lol. Like you said the outside of the flange vs the port, you could see daylight lol. So it went on 273 for a short stint lol. I love the looks of them. Intake gasket is Felpro 1243 273/318 size. Orange...

I've been eyeing this cam but thinking maybe 108 centerline? Also maybe going solid. Expert I'm not. 340, 10 over KB pistons, 160 cranking pressure 10:1 Comp (I believe), Eddy heads, RPM intake, 750 ABS carb, Stock manifolds 2 1/2" Exhaust, 4 spd., 323 rear gear, 235/60/15 tire. Street car with...

For Sale: One nice used set of 1968 through 1970 340 HP exhaust manifolds. Heat riser dial in place but butterfly removed. Little to no pitting on these nice shape....No visible cracks or repairs anywhere that I can see. Removed from a 1969 340. Ready to run. Passenger #'s are 10-6-8 2863549...

I have a set of 340 hypo manifolds $600. Thx

Looking to sell large lot of mopar parts that belonged to my Dad....partial list below. Will be adding to it as more parts are discovered and cataloged. intake manifolds 4 barrel mopar original 1827899-1 440 4 barrel 2951736 225 2 barrel and carb 4041043 exhaust manifolds 4173166 1981...

To my knowledge Offy never built a dual plane. The 360* is the designation for a single plane. IIRC all of their V8 intakes were marked 360*. I have one sitting on the top of my 360 in my work van. It has the 318 sized ports as the manifold I wanted was 340/360 specific. It ran fine with a Comp...

Just my opinion, if you don't want headers, it's not worth the extra 60 cubes to choke through exhaust manifolds. I would build the 340 to do what you want.

Hi Folks Running a 340 auto with an XE262 cam, 1969 HP manifolds and a factory TQ on a 1971 Demon (3.23 gears). Looking to purchase a 2 1/2 TTI exhaust and see that there is an X option and an H option for crossovers. I am looking for something with no drone on the highway, and not...

Hi everybody, I have a 72 Plymouth Duster with the 340 and I'm trying to find a pair of stock exhaust manifolds. Does anybody know where I might find a pair? Thanks, Paul

Fair but if you're after a nice street ride, they aren't a bad option. Given the choices later A bodies have I'd easily opt for headers of any kind, but with the premium on early stuff, off... I'm a cheap *** so... lol

You can find 72-74 340 / 360 A body manifolds at pretty reasonable prices and just order head pipes that fit the manifolds you use. They are not nearly as expensive as the 68-70. That is what I did on my 69 Cuda with a 360 / 727. I sawzalled the headers off. I ordered my exhaust from Waldron &...

What do the current plugs LOOK like? They'll tell you all you need to know.

I swear I bought a pair of repops last year $600 ish? to replace some older ones that I had welded a crack on the lt one and had to remove what ever that stupid back pressure pos that was rattling on the rt. And I’d like to put it out there for all those guys that say you can’t weld cast iron...

Yeah, you didn't see problems like this with the stock large gear reduction starters Chrysler used. Like I said earlier, the only reason I'd go to a mini starter would be lack of space.

...can be a pain. If you have a stock or mild build and you aren't trying to squeeze the last ounce of power out of it, a pair of early 340 manifolds would work fine. There are also combinations of newer manifolds (like later model Jeeps with Magnum engine) that have larger outlets for more...

how have your exhaust manifold gaskets held up. any issues?

Wow - through exh manifolds to boot!! That's just awesome!!

Can you post the numbers on the manifolds? I'm interested if they are 340 manifolds.

I already told you where I’m at and I run an MSD7AL3. My 72 (340) duster came with electronic ignition. When I told out local Mopar guru that I had to climb a local hill and jump on it in third gear and get two backfires out of it these were his words. Get rid of the damn Champion plugs and put...

Complete will fit manual or power steering a bodies, $350 plus shipping from 91770

When I had my stock 340 in there 600 Holley some under steering linkage headers, 2 1/4 exhaust, stock 1 5/8 inner diameter chrome tips, 323s, street radials, some crap mufflers, it usually ran 14.2 to 14.0. One time at Cecil Co track it went 13.90, it hooked, all the stars aligned, tail wind...

Yikes unbolt the head pipe everytime F that lol i will stick with the 90 degrees thanks for the info
