Anyone Transplant a 340 into Their 68-70 Runner/Charger?

Motor will drop right in. Shouldn't be much to get it all to work. Youll need a small block transmission/bellhousing depending on auto/manual.
 
I'm surprised the factory didn't put them in originally.
 
The 340, and later 360, were primarily for the a body cars. Not enough oomph for the heavier b body cars during the heyday. Only until 1971 did they offer it in b body cars. During the gas crisis, we actually did replace big block with small block in a few instances.
 
I've got as '67 Belvedere with a 318. I am seriously comtemplating a mild 360 for it. Then there is my buddy who is trying to talk me into a stroker crank for that 360 to make a 408.

STROKER!!!!! STROKER!!!!! STROKER!!!!! :thumbsup::D:D

Yeah, I know. The only thing that is holding me back is that by the time I build the motor and upgrade the transmission, rear end, exhaust, and possible the cooling, I would have a pile of money into a 318 car. You guys understand, right? Afterall I wouldn't want to be the first guy in the history of old cars ever to have more money into a car than what it was worth.
 
my 71 charger has a J head 340 out of a T/A. plenty of oomph for the weekend warrior. not saying you'll take it down to the track and win every time but she certainly makes the tires bark in 3rd. it does look a little small when you pop the 6 foot long hood though haha
 
there's an older pic i have on the work computer.

This is where I say....If you have the parts (crank, rods, pistons) then use them. As soon as you have to start buying those might as well go stroker if that happens.

While the above is true, it's also true that you could get the dimensionally similar 318 (or even a slant six) in the '68 Charger, so slipping a 340 in would be a piece of cake. Or pie. Or perhaps strudel. But it wouldn't be a challenge.

The 318 was the bread and butter engine for the b bodies. But for performance, the 383 4-bbl was the starting point.

A buddy has one that easily makes more power and more torque than my 451, though mine is a fairly mild build.

Thing is a real monster.
 
I used to work with a guy that had a 70' Charger with a 340 in it. Man, I wish I would have bought that car back in the 90's. Very solid car that he brought back from California with him.

I agree, had a X head 340 out of a 70 Challenger that I dropped into my 73 Charger after the 318 shucked the timing chain, wish I went with the 360.
 
My 70 Satellite was born with a 318...motor was long gone when I got the car...I transplanted a stock 1970 383 in there when I built it...I should have put a 340 in...My 340 in the Dart will run all over this 383 all day long....There is no comparison...

Apples to oranges brother. Stock for stock the 383 only puts out 15 horses more than the 340 but it does put out 60 more ft lbs. torque. than the 340. With that said and with the cars in stock build the Satellite weighs approx. 630 lbs. more than your Dart. No doubt your Dart will walk away from that B body... The 340 doesn't have the torque to get all that weight of the B body moving. IMO the 340 is a great high revving motor that works well in A or E body cars, not so much in a B body, I'm sure I'm preaching to the choir though...
 
My apple's suck...I should have gotten an orange...
I enjoy driving them both...I've come to the conclusion that you need a car for every occasion...
The green one will go 250 miles or wherever to a show and cruise around anywhere you want...
It probably gets 5 or 8 times more miles put on it than the Dart...
The Orange one will get you light to light and has more old school vibe...Ran 12.32 a couple years back with a few small issues...
If chit gets deep I can always go grab Dad's 416 Duster...
A little more attitude in a sleeper vibe...
Should be a solid mid 11's but haven't stress checked it yet at the track...
