Fluid Damper

I've thought about a fluid style damper but don't know enough about them to spend that much on one.in the past when I have had a bad damper I've headed to the junkyard and gotten my replacement
But as luck would have it they don't have a single forged crank slant 6 in the yard right now.
So I sent that one in and a 318 one for my son to go on his internal balance 408
