Poll for Minimum Torque for a performance street Machine?

Too many variables. I enjoyed my stockish Commando 273 (what's that? 280 ft lbs?) with the four speed and 3.23 gears. The stock 340 is near perfect, but the stock 440 IS perfect.
Is your 273 an early A?

340 in later A's and 440 in B and E bodies, ultimately were really talking about power to weight.

People are always talking torque, was just curious what they thought was minimum for a performance street car.

Ultimately it's average hp at the wheel, torque rpm and gearing sorts itself out.
