Max Torque Big Block

Torque is almost a pure function of displacement, NA, as said. Buy the largest stroker you can get if you want torque. A 4.25 or 4.5inch crank in the 440 block with a cleaned up set of factory heads, good exhaust valves, HR or hydraulic flat tappet cam and you should be happy, except at the gas pump. S/F....Ken M
