318 to 360 brackets
I put a 360 in a '68 Dart that had a (non original) 318 in it. It still had the '68 model 273 water pump and power steering pump. '70-up water pump won't work unless you have a '70-up radiator since the lower hose is on the driver's side on a '68 and passenger side on a '70-newer. I just used the original '68 style water pump and everything worked as usual. The only problem with this is the the '68 water pump lower outlet covers the timing mark on the front cover unless you change that to a '68 model, too. (I didn't).
Here are a couple of pics. Sorry the one you need the most is blurry.
