3.27s... what to expect?

What kind of gains should I expect to see at the strip if I swap my 2.73s to 3.27s? I've heard a couple people say 3-6 tenths depending on the car and driver.

Also, does anyone know of a place that has a good price on an Eaton posi for these cars? The ones for 5.0 Stangs should bolt right up, no?

you can expect the front end to come off the ground 3-5 inches...haha yea maybe not that, but you will see a few tenths drop
