    I would not mix forged pistons with cast.
    on a .010 overbore???? I would not worry.

      Wiseco offers three oversized pistons for your engine. Very good pistons, have used them myself.

      I would ask them the weight of the piston before ordering and compare the difference between your original pistons.

      They are drop forged pistons, not cast like the originals, making them very durable. Used for racing engines.

        like I said.

        forged are more prone to cold seizure failure.
        I have had good luck with OEM and sierra pistons.

        forget that race bubba stuff.
        unless your trying to twist 9000+ RPM cast work well in that motor.
