Flathead 6 is toast. Anyone swap a jeep drive train into 49 Windsor.

Measure the head front to back on your Chrysler. Should be 25". Next do the same with the truck engine. Will be 23" with a lot less horse power than your original engine. The shorter engine can be made to fit but will require modifications. You need to find a 25" engine.

[RobertKB]

I agree with Don.  You need to find yourself a 25" engine. In the long run you will save much time and effort. The right length engine is a straight swap with no modifications needed. You will not be happy with the shorter engine in the Chrysler. Yours is a problem we never have in Canada as ALL Mopars built here since 1938 through 1959 have the longer 25" engine which makes finding a replacement very easy. Too bad you are not closer as I have two good engines in my garage looking for a home. Good luck with your project.

Look around for old Massey Ferguson/Harris combines. They used Chrysler industrial engines might find a long block languishing there out being the equipment shed.

@Becuzican: what did swap the engine with?

[Becuzican]

Dodge 230.  Made some new motor mounts from 3/8th in steel and it went right in.

[Dodgeb4ya]

That dodge engine doesn't have the torque or power needed for the chrysler IMO.

[Becuzican]

The same for the most part.  Lighter engine,  compensates.  Either way, not hot rods.

[dpollo]

It will work and it will fit your Fluid drive unit but it is 2 inches shorter.   Better to go for the big block, another 251  or better still a 264  from a 53 or 4.  These will give better performance in a heavy car.

[Becuzican]

It's already in.  Am done with it.  Trying to get rid of it as not my favorite car and is taking up space.

[Plymouthy Adams]

hope full disclosure goes with the sale...

[Becuzican]

WTF is that supposed to mean... you think you got a reason to insult someone and start some ****.

If someone buys a Chrysler then they have a right to expect a Chrysler engine unless they know in advance it is not original. Not everyone who might look at the car will be as smart as you and can tell the difference.

I had forgotten all about that.

Wasn't that the start of the downfall of Oldsmobile and Pontiac? WTH would class-conscious geezers spend the big extra bucks to buy a Pontiac or Olds,when it was just a Chevrolet wearing a fancy dress?

[Dodgeb4ya]

I'd sue if I found a little Dodge six under my Chrysler's dress!!!!

It was probably the early start of it. Pretty soon the drivetrains were all the same and it was just different on the outside. Like my Mazda that's mostly Ford. Even the dipstick says FoMoCo
