Poll for Minimum Torque for a performance street Machine?

I doubt many would say under 300 lbs-ft is acceptable for a V8 and to me it's quite obvious 400+ lbs-ft is more than good by what cid people generally build, but there's got to be a line somewhere in the 300's where generally people find an engine lacking, obviously there's many variables there's really no way to factor all of them in.
It whatever you think based on your own qualifiers, you could add them in as well.
