"This MBE cylinder head for Alcohol and Pro Mod is a complete game changer."


MBE new cylinder head for Alcohol and Pro Mod racing is completely changing the game. This clean-sheet design is new from the ground up and so radical that MBE has to cut each head from billet aluminum rather than modify an existing casting.


MBE head is designed with ultimate port flow in mind for unmatched power. The intake, in fact, flows an incredible 590 cfm, which is 60 more cfm than any other head for this class. On the dyno, this improved flow translates to race engines producing 110 horsepower more than any competitor’s head can manage.


MBE’s Alcohol/Pro Mod Hemi head has already garnered a championship and consistently produces the top mph mark at ARDL races. To get this incredible level of performance, MBE had to make changes to everything from the valve sizes to the port locations, but this is what’s required to make the ultimate power package for these racing classes. And the advancements are substantial all the way across the board. While the peak flow numbers are astounding, the flow at all valve lift levels are just as impressive. And by cutting this head from billet, MBE is able to produce a stronger, more stable cylinder head that eliminates weak spots and many other problems associated with cast cylinder heads.


To squeeze the absolute most power out of your engine combination, MBE can also help you develop a sheet metal intake precisely tuned to the requirements of these heads and the rest of your engine package. To put it simply, this is the best Hemi head for Alcohol and Pro Mod racers you will find anywhere.
