time is all depending on if you have all your tools readily available, and you dont lose and bolts and crap like that. I can tell you Both myself and my brother swapped my motor and had it running in one day and that was the first time that I had EVER done a motor swap but I was very familiar with my car. You need to get an engine lift (I call it a cherry picker lol) and a chain so that you can pull and install both the old and new motors. Just take it slow and make sure you do everything the correct way and you should be ok.
Also, you need to get a service manual because this will tell you how tight everything needs to be torqued down and what not...
