After dominating Northeast Big Block Modified racing for the previous decade, MBE has just introduced the cylinder head that will continue that dominance for the next 10 years!
Known simply as the “Next Generation,” this cylinder head boasts performance advancements in several areas. After an intense R&D program, MBE has moved the intake guide bores from the traditional locations. This change improves mid-lift flow numbers which will help you make more passes coming out of the turns and off restarts.
MBE has also raised the intake ports to further increase this head’s already class leading ability to flow air and fuel. And to really get an unfair advantage on the competition, MBE has also designed a custom ported cast aluminum intake that takes advantage of the new raised ports for maximum efficiency. The intakes flow an incredible 430 cfm while the exhausts can handle 305 cfm.

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.
