    Dear Sirs,

    What is the ball park price for:

    8B 5025: 4.585 Bore / 1.0 Raised Cam Location / 11.625 Deck Height with extra machining for a 5.75″ crank

    And can you make a V12 version of this? How much more?

    Thank you,
    Wally

    • Brodix says:

      It will cost approximately $7450.00. We do not offer an additional clearance program for the 5.750, the block will accept it but you will have to do it yourself. We don’t do anything for a V12.

      Thanks!
