New Big Fin M2 and M3 Heads: (Patent Pending) Available In 2009. (Click here for Photo)

The M2 & M3 Heads represents a completely new approach to the problems associated with the stock and aftermarket 45-degree v-twin design. Developed by Kyle Mathews, Joe Mondello, and Darin Morgan, this port design is used in today's fastest NHRA Prostock Car and Motorcycle engines. The ports capability is limited only by valve size and has been developed to move the most air possible while maintaining the necessary air velocity. In addition to air flow capabilities of over 330 cfm with a 2” valve. Valve geometry had been addressed and push rod tubes have been moved for additional clearance.

The Patent Pending manifolds for EFI and Carbureted engines induces swirl or mixture motion equal to that seen in NHRA Prostock engines, the most efficient naturally aspirated engines in drag racing today.
