swap a 273 for a newer magnum 318

I want to swap out my old 273 in my 65 barracuda 4speed for a 1999 318 out of a dakota. Will I just be able to swap out like an older small block or what. Are the motor mounts in the same position and will the 65 4speed trans fit properly?
I can get the motor for a good price and it has low miles. I know I will have to get rid of the fuel injection on the motor and replace the ignition. Any other issues?
