    crankshaft balancing question.

    Question guys I bought a crank that was balanced for*9.5:1 cp pistons, Carrillo rods.

    Can I just toss stock rods and pistons on it and go or do I need to have it balanced for the new rods and pistons?

    You would need to rebalance if using anything other than what the crank was balanced for

    Whats balancing cost? Might just get a stock crank and do all stock internals.

    you should be safe doing this, but you will need to match the weights of the new set up.

    match the weights to each other, rod ends and pistons.
