Poll for Minimum Torque for a performance street Machine?

IMO;
At speeds below 50 mph;
it really really really depends on your gear ratios, the weight of the vehicle, and the application.
I voted 360 minimum, cuz it allows a three-speed Torqueflite and 3.23s
But;
What I actually want is a minimum of 400ftlbs x roadgear of ~6.8 (manual trans), in a car weighing up to 3600 pounds(me in it). Doing the math, that comes to ~.75 ftlb per pound of mass to be moved, at 40>45mph. This is where the fun is, I can always lift if it's too much. But if it's not enough and I run out in mid-turn, aborting can be embarrassing if not dangerous.
400 ftlbs at 3500 works out to 267hp. By 4000, it is up to 305hp
It took me a lotta time to find the right Roadgear for my little 367.
Whereas with a BB or a stroker , you can just put it in Drive and go, then dial in whatever you need, by throttle-position..........
Too much Torque?
For a NA SBM, not stroked, in a big-tubbed A-body, I don't think there is such a thing. But a boosted 360/or a stroker, could be serious overkill, in any small-tubbed Dart.

These are my opinions
