On a more serious note, I ran low 10.0x in a 2850# (me in it) '66 Mustang with a 520" pump gas stroker tube chassis car with 18" wide "street" slicks.
...it made 667 HP and over 600 foot pounds of torque throughout its entire useful RPM range. It had a 4800 RPM stall converter, transbrake C6, 9" rear with 3.89:1 gears on a spool and plenty of traction. You need to ask yourself how close your LTD is to a car like it.
