A body weight?

Mid to low 10's, you will need about 550hp or better at that weight (assuming you are at 3100#'s car and driver).

I don't know what power my car makes (never checked), but it pushes my ~3250# Barracuda into the low 10's.

That sounds about right ! I made 549 hp. with a relatively mild W2 head 363 went 10.40 in a 3,150 lb Dart.
