Of all the real stupid ideas, putting a one barrel card on a v8, you would think just to get decent mileage they would put a 2v to get more air.
But here are a few questions, I was a ford freak, so please be kind.
My ramcharger has a 318, would a 340 bolt in with no problems, if I can't find a decent 340, can I put 340 heads on a 318? Would it help performance.

318's were used in a lot of boats...[;)]
Yep, and not necessarily the power plant....
I would love to have an old dart or Sebring with a 318
You could buy a new 340 block for about $2400-$3000 and then put a ton of parts in it. A used 340 block is at least a grand, if you can find one, and usually bored to the max or very close. If you have a buddy who has a 340 with low cost then the 340 would ok.
Lots of 360's around and fair prices to boot. Check out some of the Mopar forums, there are plenty, a google search will get you several.
A far as fitting, the block exteriors are the same. The tranny may need an upgrade to handle the extra torque and HP from either motor. Questions of this nature are always answered better when year, model and tranny are indicated.
Good Luck![:)]

318 was one of the best engines ever built in my opinion, I had several, never failed me ever, I got over 400k out of my 73 dodge van and sold it still running, the guy I sold it to ran another 30k and sold it, I helped him repo it and drove it 20 miles with no coolant in it, and it still ran for years
Honestly, I've also heard this too about the 318.
Damn Straight. I had a '73 dodge charger with a stock 318 that would snap solid steel motor mount if ya let it.(and I did,too) Couldn't stand the noise or vibration of the solid steel so went back to stock rubber and chained the engine right before the snap point. Dam good engine. Sure miss her.
If you are going to change motors, go for the 360, as a 340 is a good motor, just try and find one that is useable, and when you do, be prepared to shed lots of $100 bills. Dollar for dollar the 360 is better, hands down.

+1, the 360 is cheep and plentiful as well as being a drop in
Using 340/360 heads on your stock 318 will decrease the compression ratio making things worse. Also, no production 318 in a dodge truck or car came with a 1bbl carb. They were either 2bbl or 4bbl.
The 318/360 engine family are very tough and reliable. I took a bone stock 84' 318 and fabbed up a GT45 turbo with a 800cfm thermoquad feeding it. It's seen 536hp and 586ftlbs at 24lbs. of boost. The only modification I made was to O-ring the deck and install copper headgaskets. Dave
The 318/340/360 family of engines is among the best ever offered with the possible exception of the Slant Six. The little carburetor on the 318? Economy was a consideration as was torque. The little carb was a pretty good choice given its intended use. You'll find it on trucks quite often.
A 340 in place of a 318? Expense aside maybe not the best choice. The 340 is a performance motor. Torque curves are totally different and the 340 just isn't an ideal drop-in. I know as we temporarily put one in a Ram Charger. It sounded mean but without the proper torque converter and gearing it was a total dog.
The 360 on the other hand comes in many flavors, is common, and is fairly cheap. Even one with a ton of miles is inexpensive to rebuild. The 360 will have the attributes of the 318 or the 340 depending upon the build. The main difference being economy as the 360 tends to be more thirsty than the 318 under the same conditions.
So to your question... While the entire family will directly bolt in, it may not be in your best interest to do so without knowing the repercussions as these can be very different engines.

My first car was a 1971 Dodge Dart Swinger with the 318.
Great little car. Plenty of power, decent mileage, accepted the abuse of teen aged driver fairly well.
Had it airborne a couple of times, once for almost 100 feet.
(It did need a little front end work after that one.)

A co-worker inherited an all original 2 door Dart with factory 318. His neighbor willed it to him, he was with his neighbor as a kid when the fella went in and ordered it. Its green with a green vinyl top and green interior. It is cherry...he has all the original paperwork and every single inspection sticker and receipt.
My ramcharger has a 318, would a 340 bolt in with no problems...
Yes the A series blocks are the same. Heads will fit.
Why not just install a new 2 or 4 barrel center head?
If both are LA motors no problem. If you build it to a 340 you may have to change the torque converter on an automatic. For the 318 has no weight and the 340 has one.
Cant remember which is which. But on one side of the engine (left or right) all of the part numbers are even and the other side are odd.

My dodge had a 318. Great power plant that thing. Got 18mpg pulling or empty and never lacked for power.
And fiery auto crashes
Some will die in hot pursuit
While sifting through my ashes
Some will fall in love with life
And drink it from a fountain
That is pouring like an avalanche
Coming down the mountain

I am looking for a intake 2v or 4v, got to get more air, who ever thought of a 1v on a v8, poor mileage, poor performance.
I have a 1984 Ram short bed street rod I built. it ha 318 with light racing cams and a 2BBL Holley. I get about 10MPG. I have a 4BBL on her however I got half that mileage. Problem may be because it sounds so good when I gun it. I run premium reg gas in it as it likes
If your mileage was that poor there is something wrong. Proper component selection is critical, everything has to work together. Did you ever tune the cab with a wideband A/F meter?
The truck in my signature features a 605ci Hemi, runs on 89.5 octane, makes 853hp and 818ftlbs. Also has a 10" race convertor and 4.56 gears out back. It gets 10mpg if driven nice.Dave
My '89 Ramcharger has 318, power seems adequate, lots of weight for the size.
Slant six was engineered for long life but de-tuning for pollution controls kind of torpedoed its advantages.

You can find 1966 and up 318-340-360 small block 4 barrel intakes all over the web for sell cheap.
