BRODIX® Introduces the BP RR BB-3 XTRA O™ Big Block Chevy Head

7 Comments / Press Release / By

With the introduction of the BP RR BB-3 XTRA O, BRODIX® pushes their popular Race-Rite® series to a new level. This 100% CNC ported head features a new 24° valve angle, as well as a 298 cc intake port that amazingly flows over 390 cfm! Other features include: newly designed, stock height exhaust ports that flow over 280 cfm, 2.300/1.880 valve combination, and 75 lb weight saving over iron heads. As with previous Race-Rite offerings, the exhaust ports remain in the stock location eliminating header or manifold interference. The Race-Rite series is the answer for less hassle during installation.

    When do you think we can get some more info on these heads in process of final part selection for a pump gas hydraulic roller 509

    These sound like the perfect head for the 496 Street Rod. Is the intake runner 298cc after
    the CNC porting or before?

      It would be a good choice if you are looking for a fully CNC ported head, the 298cc is after porting. Another good choice is the RR BB O or the RR BB R.

      Thanks!
