Narrative:
We received the final weights via the ACARS printer. The trim was set as called for and verified. As a cross check; I entered the mac on the takeoff page in the FMC and it's trim setting was very close to the final weight message. During the takeoff roll; with V speeds properly set; I attempted to lift the nose off the runway at the rotate command; but it was very hard to do so. I had to pull very hard and had to add nose up trim. The nose finally came up. During manual flight I noticed the aircraft difficult to level off and after adding trim inputs; it was if I was over trimming. It seemed out of balance.
