  1. Harmonic Balancer

    Engine
    I have a 350 sb I'm putting together and it came with the 8" harmonic balancer but a lot of the rubber in the ring is missing and cracking. Is this fine? I also have a 6" harmonic balancer from a 305. If the 350 one is not good enough, could I use the 305 or were they balanced different? Thank you.
