If you are keeping the OEM harmonic balancer, there are two different styles for the late model engines, a small solid hub and a larger rubber one.
I recommend you do not use the solid hub for racing. Although is small and lighter, it does not dampen the harmonics as well as the larger two piece with rubber. With the block having hollow mains, the dampening of harmonics helps the life of the engine.
If you will not be using an SFI balancer, I recommend the Pioneer Part Number DA-4552

We just finished balancing with small balancer. I have no problem buying the 2 piece but do I need to rebalance? My guess is I don't need to.
