273 or 225?

How easy would the 273 to 318 swap be? Any modifications to the body/frame at all? Also lets keep in touch about the hood.
Off topic, but if that 65 has a hood on it in decent shape, I’d buy it from you. I’m just over near Sacramento.

I’m building a 225/4 speed 65 Dart, if I wanted to go V8 I’d start with a 318 magnum from a junk yard vs the 273. JMO.
