Installing LCD to cement block

I'll be installing an LCD television for my mother in her basement, and it's getting done on an exterior wall, in which the construction is 1/2 inch drywall backed by furring strips, then cement block. There's maybe a good inch between the drywall and the block. I plan to drill through the drywall, lined up with a furring strip, then into the cement block with a hammer drill and a 3/16 inch cement drill bit then using 1/4 inch x 2-3/4 inch long Tapcon anchors. I also understand that the cement block is hollow with maybe an inch or inch and a half of bite. My question to you guys is, will 2-3/4 inch length anchors be long enough? I plan to use 6 to 8 of them, 4 of which will be lined up with the two furring strips 16 inches apart for more snug of a hold.

The television is an LCD and weighs approximately 60 lbs. I plan to use a rack with the tilting feature, not the pivoting arm. TIA :)

If it were my house I'd build a second wall in front of the first, but only to the width of the flat screen maybe wider if you want to install some in-wall speakers. And you would be able to conceal all your wiring and add extra outlets and low voltage boxes for your speakers and cables.
