//5.000 Inch Bore Space (Brodix)


It’s no secret that big engines make big power. But if you want to make the most power you have to have a cylinder head that can feed the mammoth amounts of air and fuel those engines require--and that’s a lot easier said than done. As drag racers are pushing their big-inch engines to ever higher rpm levels, the amount of air and fuel that must be moved skyrockets, and that’s where most cylinder heads suffer.


MBE’s brand new 5.000-inch bore space cylinder heads based on a Brodix casting use proprietary discoveries to make incredible power. To feed the giant drag racing engines now in vogue, these heads are capable of flowing an astounding 594 cfm through giant 2.570-inch intake valves and 378 cfm out the exhausts fitted with 1.820-inch valves. The trick is an asymmetrical layout that tunes each port individually for maximum flow. And remember, MBE is the only induction specialist willing to stand behind its advertised flow numbers with a money-back guarantee.


This cylinder head can work with either a fabricated intake or a cast manifold. MBE even offers a ported cast intake designed specifically match perfectly with this head. This makes it a fantastic option for Nitrous Top Sportsman as well as Super Comp and Super Gas (S/C & S/G) racers looking to get a significant edge on the competition. These cylinder heads are also very competitively priced when it comes to 5.000 inch bore space cylinder heads, giving you the best bang for your buck anywhere.
