18 degree heads on top of a bullet proof Dart Steel block.. This engine will make big torque with a

super smooth flat torque curve. The flat torque curve we have developed allows this engine to be very

drivable in the slick yet when there is moisture on the track you better hang on, because your going to

be the fastest on the track. This engine is for the racer that has his chassis working real good and

wanting to compete with the best in the business.
