Which engine would be easiest for my swap?

Going to do a 360 magnum swap in my son’s 67 Dart. I have two engines available. One is out of a 1993 1 ton with a manual transmission. The other is about of a 99-2000 1/2 ton with automatic. I want to use the stock fuel injection. Which engine would be the easiest to do this with? I’m thinking the 93 would be, but not sure. Also the 93 has fewer miles and I know more about that engine because it’s out of a family members truck. Any advice would be appreciated.
