Late 80's /6 swap to 73

My slant is tired, and I think it may need a headgasket. So rather than fix it I'm hoping to do a quick junkyard swap.

The only one in town is from a late 80's truck. I know these have the hydro lifters, and probably all around worse than earlier motors. But will it bolt on to my 73 Dart with much trouble?

I'm not going for performance. I just need a good daily driver for the summer. Hoping theres enough slanters here who know about these :)
