Swapping Hard Drives, RAM

[DockMac]

I have a Black MacBook Late 2006 running Lion and a MacBook Pro 13 inch Late 2009 running Snow Leopard. Would I be able to just switch Hard Drives on the two computers and have them boot up with no additional tweaking?

Also, just to double check it's compatibility, I am able to take the RAM from the MacBook Pro and put it into the Black MacBook, and vice versa, with no performance hit?

Could work. Just give it a try and you will see.

FYI. Just did it. Swapping HD's works flawlessly.

Hard drives should work, the RAM will not as it is a different pin configuration and type.
