MBE’s P5 Dodge Hemi is a great example of an engineering exercise taken to the extreme. The Hemi is are already famous for great power production, but MBE has created a next-generation design that combines the raw power production of the classic with the latest advancements in induction theory to create what MBE owner Matt Bieneman calls, “the most efficient cylinder head that we sell, period.”
The P5 Hemi utilizes every trick in MBE’s extensive book to create incredible flow potential. This head features valve angles that MBE keeps confidential, and when equipped with Jesel’s rocker arms designed especially for this head the pushrods angles are perfectly straight. The chambers can be sized anywhere between 25 and 45 cc’s and are cut to accept 2.280 intake and 1.600 inch exhaust valves.

is the leading induction specialists in the country, with cylinder heads and intake manifolds used in championship winning programs from NASCAR Nextel Cup, to NHRA Pro Stock, to Sprint Cars to Dirt Late Models and more. MBE is the only CNC porting company to guarantee cfm flow numbers for every cylinder head it produces—and those numbers are often the highest you will see anywhere. MBE maintains an aggressive R&D program and constantly updates its cylinder head and intake profiles to stay ahead of the competition.
In racing, there is no “one size fits all” solution, so MBE custom fits port and chamber designs specifically to each racer’s application. This even includes custom port work on intake manifolds to make sure the entire induction path is optimized for the engine. It’s all a part of MBE’s commitment to you: Power through precision.
