What would you expect to be the benefits of a 6.385 con rod in a 3.76 stroke motor ? Could there be balancing issues? and how much power can a forged gm 427 crank take? Do you think a striped 671 will out perform a non striped 871? The reason I ask is I am considering building a 427 for my drag car and I have some parts that I would like to use up. Thanks.
