1992 318 dakota motor/trans ---> 65 dart??

the 318 will fit but you'll have change the oil pan and oil pickup tube from a car. You'll need different motor mounts (If it's a slant 6 car) and exhaust manifolds (if the 318 is not a magnum). I'm not sure about the trans however. If it is a slant 6 stant six car you'll want to beef up the stock suspension.

I got a lot great advise from the forum on my swap here's a link to a thread that should help.
