Need Help Quick. 400 stroker build or 440?

the money is not the biggest issue.
I have tons of room to put what ever I need in the car.
I just want a solid hp machine with big torque.
this is my old bracket cuda. it has got more fiberglass than steel left on it.
The drive trail will hold what ever I through at it.
my main question is-- is a faster rapping 400-500 stoker better in a light car than a lower rmp, slower spinning 540 torque monster?
