273 parts

I have a 273 motor in my car now.Needs to be rebuilt.I'm debating if I'm going to keep it or put something else in.I'm new to these mopars and I have talked to a few people and some tell me that these motors can be built to run decent and others that have told me not to waste time(as in not enough power) rebuilding to just go with a 360 or something.So now I'm now sure which way to go.
