Harmonic Balancers

I think I'm going to try the Trick Flow one. At the point where this motor is at, I just something stock-ish that will hold together. The 48 year old one on the motor now looks a little worse for wear.
I have the trickflow. My only complaint is its painted, not powder coated. At some point the timing marks/numbers will dull, or surface rust. I thought they were just dirty and used some brake clean on it.....and wiped the paint/Marks right off. :/ dummy me

Edit: Yes they are etched....but still near impossible to read if you pull a mr clean like I did
