318 swap to 440

[Iowa Six Barrel]

I have a 70 Challenger SE. It came from the factory with a 318 and a 4 speed transmission. Am I correct that the K frame from the 318 would also take a 440.  I thought the only K frame swap is for the slant 6 going to any V8. So, all V8s use the same K frame - difference being a 440 k frame has the skid pad welded to the bottom of the K frame to protect the deeper pan.

True the K frame is the same & also the trans crossmember & mount , as you said the skid plate was added to protect the deeper oil pans & can be added to any K frame

not "all" v8's.........The Hemi uses a different K Frame 

...but yea,....you're right, it's a pretty simple swap.....you might want larger torsion bars...

[Chryco Psycho]

You can mount the Hemi also just need special mounts & headers to fit .
Not the factory way but I have done it .
Even the 3 gen Hemi will bolt in with the right mounts & headers .

or not if it's gonna be a 1/4 mile car.

I just did this swap over the winter, my first ever engine swap. It was pretty darn easy and I had no clue what I was doing going into it...

Just get ready to get nickel and dimed to death on all the little things that won't transfer from the 318 to the 440.

Hence the mopar $$$ pit.

But at least you have something that isn't really seen very often.
