Here's what I came up with:
Take-off distance to 50 feet - 1900 feet (Both engines operating)
Accelerate/Stop distance - 3600 feet (86 knot decision speed)
Landing distance from 50 feet - 1725 feet (Vref 79 knots)
That's using Gross Weight (26,900 lbs.), sea level at ISA (15 C), a paved, level runway with 15 knots of headwind (and photocopies of really old charts taken from a few different sources).
