    Copper is superior as re. dissipation of heat and it is used on some rods for this reason.. These copper ‘small ends’, in some applications, have been designed to operate without any bushing.
    ‘Rod ratio’ is very, very critical in determining torque to be available at a specific RPM range~ Are you conversant with the Hepworth-Granger formula?

    Can you do Triumph 650 m.c. heads?

    Nice work~ You are most generous in sharing your knowledge.

    question….how can the billet rod be forged and machined? is it forged then machined or is just machined from a billet?

    Thank you sir. This video has answered questions that have been bothering me for quite some time. It’s a whole lot easier to learn when you can hear the tone of someones voice, not just their typing.

    The cam galley however it worked think the cam galley however it worked think the bore of core shift.
    The bore of the block had little bit of the bore of core shift.

    thank you very much, its nice to see such a clear, informative and professional video on engine internals

  21. fiatnutz on July 22nd, 2009

    Not lately. Did the bearing seize to the cam? What did the journals look like? Sounds like it’s time for some green Loctite.
    JE…

  22. enginemasterbuilder on July 24th, 2009

    ABSOLUTEly perfect vid . great refershment of whats going on in the life of engine rebuilding. have you had any 440 dodges in laely where 5,6 cam journal has turned in its bore and blocked the oil off to that area of the engine?

  23. enginemasterbuilder on July 27th, 2009
