fliuldamper are the biggest piece of shit ever made for real race engines...ask any pro engine builder and you will get a ear full why there a pos!!! try balanaceing one.. ever time you spin one the balance changes so you can't get a rotating assy to come out right. so if the balance changes every time i shouldn't have to tell you the problem's it will have. broken cranks, bearing all f--up, bad enough to brake a sbc oil pump houseing,etc etc... seen it over and over again......
