C.A.T. Fluiddamper?

I got one in chrome, looks great. Fit and finish is A1 (tight as F on the crank snout though) get the 135 ft/lb torque wrench out. Its a heavy **** and thick as a phone book. They say the intertia ring 'floats' so its not really rotational weight...Yeah, OK.
I got one with a 340 i bought ,and yes.it seems to be a very tight fit in the crank. Guess it's ok to use then. Thanks for input
