Ford 331ci
With the ultimate rod ratio in a 302 stroker the 1.696:1 331 stroker features the same offset wrist pin design as the venerable 347 Street Fighter. It is also benefited by the 1650 gram (approximately) bob weight, making this stroker one of the best street and strip engines of all time.

50 STATE LEGAL!
The 347e installed in a late model Mustang with factory heads will deliver about 330HP. Add a set of aftermarket, 50 state legal, cylinder heads and run about 380HP. This combination provides a smooth idle and broad torque curve, which makes it perfect for a late model Mustang slated for daily use.
