Our 331 Ford is short and sweet. It is a great RPM motor with plenty of torque and horsepower. Because of the shorter stroke, it’s improved rod angularity over the 347 keeps the side-loading of the piston to cylinder walls at a minimum. Perfect for that Roadster or Mustang that wants improved performance over a base 306, but really wants to feel that torque differential in the seat of their pants.

We also offer the FD347 (3.400) stroke combination, which has similar horsepower and torque numbers.
