For your need for serious speed, get the Drag Pack. This kit harkens back to the days of big block Ford power and provides the modular Mustang engine with that same big block performance. With the Drag Pack, you'll launch harder and be faster while maintaining factory drivability. Expect to shave 5/10ths off your 1/4-mile ETs with this kit. Drag racing should be conducted at enclosed, dedicated facilities only.
