ATI, here aslo!

I was told by a well known engine builder that the ATI is the best damper because they are accurate throughout the rpm. Fluid Dampers are good for low RPM, Diesel engines accually. Some diesel mfgs run fluid dampers on their OEM engines. My machinist spun my old Fluid damper for my 360 build, and he told me it was wacky, would spinn up ok 1 time, then be way off the other time, then be only a little bit another time. I bought an OEM 340 damper for it, and it was nuts on. For my 408 build, I did a bunch of reserch, and the ATI is what I found was the most accurate.
