I came across a good deal on a low-mile 2001 5.9 Magnum engine.

I'd like to swap it into my 318 Dart, keeping the 5.9 EFI, serpentine system, A/C compressor, PS pump, and alternator. I'd also like to keep the 727 transmission that is in the car.

I've heard that I'll need to use a PS pump bracket from a Ram Van, not a problem.

I know the flexplate will need to be compatible with the 5.9. What flexplate and 727 converter can I use?

How do I make the ECU work while keeping the 727?

Will the swap require special motor mounts?

If I have correct hoses made, will the A/C compressor work with the stock 1971 A/C parts that are already in the car?

Are there any problems in using the 2001 alternator?

Would it be possible to keep the cruise control?

Car is strictly a fun cruiser, looking for dependability, a little more power than the 318, and better MPG.

Any help appreciated!

use the Magnum flexplate with a non weighted convertor
Drivers side 360 motor mount
A/C should be fine
Do an Amp gauge bypass because the Denso puts out double what the amp gauge is rated for

Swap would probably go easier using a 92-4 Dak,92-95 Van & 92-4 Truck wiring harness using a AutoMeter Speed sensor/mechanical speedometer adapter

you should be able to keep the cruise

The 318 is every bit capable of the 5.9 stock power. The swap is going to be expensive but very cool when done. I understand the good deal on the 5.9 and wanting to use it. I hate it when people tell me what to do but just an idea about the 318. I get around 325 hp out of my 318 and around 18 mpg when driving right in my 70 belvedere. I added intake, carb, elect ignition, good wires and plugs and it was not that much money. I have a 518 four speed trans and I am sure that is where the good mpg is coming from. I went .30 over when the block was at the machine shop. Good luck to you.

if you mean keep the stock efi, it will depend on the computer if it is even possible without the transmission.
there is a sensor that mounts on the back of the motor that reads positioning of the crank through a notch in the transmision to the flexplate (I think that is what it is called).

if the computer is for a manual, I think you can use it.

I did the swap on a 65 coronet, but used aftermarket efi computer on the stock engine.

the alternator uses the built in VR in the computer, but you can wire it up like any normal 2 field alt.

b&m makes a flex plate for the 727 to magnum

Are you sure you have a 727? after 67, most 318's went to 904's.

if it is a 727, the neutral balanced converter will work with the b&m flex plate.

you will need a car 360 la pan.

and as you said a van power steering bracket/pump. or it will put the pump under the battery tray.

I was able to use the durnago exhaust manifolds as well.

power steering I had to get a new hose made and a/c lines made but that all hooked up as well and works just fine.

getting hoses to work was kind of a pain. found gmc truck had a hose that would work.

I just did a 2001 5.9 w/ 90k miles swap on my '68 Barracuda. Full serpentine, still have to hook up A/C, narrow battery and modified battery tray, a 1998 Ram 2500 manual trans computer, full Summit exhaust w/ headers, stock 5.9 flexplate with a 727 from a member here, Milidon oil pan, Schumacher mounts, Surge tank, full-return style fuel sytem, US Radiator 4-core, SCT Tuner w/ Hemifever tunes, Hughes cam and springs, fully resealed the motor, modified the stock intake, upgraded injectors and a few other odds and ends.

It was a lot of work, but it's very much worth the effort! I'm running 3.23 suregrip and am going to upgrade to a 46RH with a lock-up converter some day.

Here's another shot showing the battery tray etc. The power steering hooked right up too. It runs strong, will smolder them out of first with little effort and barks second hard. Plus it gets better milage than my slant six did both around town and on the highway.

do you have a walk through on what you had to do to get the computer to work?

fully stock sensors? what about the second o2?

friend of mine did this very swap about a year ago on his 1972 Dart, 5.2 with TB efi, A500 OD auto.
He took the stock dart harness, and a EFI truck harness and put the 2 together to make one that plugs into the original dash plug.
I think his biggest hurdle was modifying the trans crossmeber and making the trans mount. But it all works. ( don't think he has the a/c hooked up yet though.

I'll get hold of him the 1st of the week and see if I can give out his email address

There is also the Megaqsuirt option. Then again, you are doing so much already, I am not sure you would want to entertain the headache of making this work as well.

Over on abodiesonly.com a guy did a really slick swap he did the engine, trans and even the a/c system from a ram with a step by step set of pictures.

Worth the read even if your not doing it
