Why on earth would you want to do that?? What is it about the 392 that you think the 440 will fix? You will definitely decrease the value of your car, get worse fuel mileage and hear hissing every time you open the hood. Nevertheless, I would gladly take the motor off your hands to help facilitate the swap. I will even trade you a good running 440 for it...so you can get rid of that hunk of iron. It even has '59 Chrysler motor mounts on it so you can drop it in place into your car.

OK, good deal. Essentially, you just need a set of big block motor mounts for a '58-'59 DeSoto or Chrysler. It is mostly a direct swap once you do that except that the transmission mount will no longer be positioned correctly. So you will have to make an adapter to extend the trans mount 2.5" in front of the trans crossmember. I made this adapter so that I wouldn't have to modify my crossmember, but you could make a more simple version if you don't mind welding support gussets to front of the crossmember.

The most annoying part of the swap is that the shifter cables aren't long enough on the later trans. If you can find some from a '62-'65 truck, I *think* those are long enough to work, or else you will need to make up some custom cables to fit properly. The driveshaft may need to be re-worked as well, I'm not sure, but most likely.

I think your in a better place to work that out, measure twice

From what I read, its a temporary swap while the factory stuff gets rebuilt

Personally, I would sell the BB you have gathering dust and use those funds to speed up the hemi build and not change anything

I think your going to have to cut things that you will need to then put back?

Ok hear your advice loud and clear, am with you that the ideal is numbered 392. So i best i go by your advice, pull my Imperial 57 engine and run here on one carb until properly restored.

Michael, I agree with others that your best route is to just tolerate the downtime as you get the 392 rebuilt.
It will keep you motivated!

I agree that swapping to the newer trans is a whole lot of trouble that probably isn't worth it unless you want to keep the newer trans in there for good. But if you were to get ahold of a good 413 or 383 from '59-'61 with the proper crank flange, then the only thing you would need to really change is the exhaust. Still a pain, but much easier to do. ....oh, and the bellhousing.

Hmmm, I used a stock '62-'64 shift cable in my '57 NY with a cable-shift 727, not sure what body it was from but they made several lengths from 42" to 59".
