I have a 1995 LT1 out of an Impala SS that I'm building. My problem is that I don't know what to do for a harmonic damper. I wanted to use a Fluidamper, but apparently they can't be used with the Impala or Corvette motors. I don't think I'll be turning enough RPM's to justify an ATI, does anyone have any reccomendations? Anyone ever used the Jeg's damper?
