Is your current damper hub keyed?
You want a keyed hub/damper and one with timing marks on it or use MSD timing tape the correct size for your diameter damper. It comes in a sheet for around $7 and you just stick on the size you need
hot engine would indicate timing is to retarded

I've had that timing tape get distorted by Carb Cleaner and come off from engine heat. It's not permanent.
You can get your Harmonic Balancer rebuilt by the Damper Doctor [ damperdoctor.com ] but for an engine as common as the 350 SBC, it's probably cheaper to get a new one. If you had a more obscure engine, the Dr would be the choice.
